Chapter Text

Katsuki Bakugo sat in the therapist's office, his arms crossed tightly over his chest. His eyes glared at the clock on the wall, each tick an irritating reminder of the time he was wasting. He didn’t need this, none of it. Yet here he was—forced into these sessions, all because of that one damned incident. 

He could still feel the rush from that fight. The high schoolers had it coming. They were messing with Deku, and though Katsuki didn’t give a damn about Deku, something in him snapped when they dragged him into it. It wasn’t about protecting Deku. Hell no. But when they called him out, questioned if he was there to save the "little nerd," Katsuki’s pride couldn't take it. He didn’t start the fight for Deku. It was for himself. 

He clenched his fists at the memory. He had put those guys in the hospital, and one of them stayed there for weeks. Thank god there was no police case, just a condition for rehabilitation. But the words still echoed in his mind: “You said to kill myself, Kacchan.” Deku had pleaded him to stop beating the high schoolers. He even went as far as saying, "Stop Kachan! Don't mess with them. You don't even care about me. They were just bullying me just like you pick on me." But when his pleading fell into deaf ears he brought up the time Katsuki told him to take a dive from the school roof. That was the moment his fists stopped. Deku, beaten and bruised, looked at him with tears in his eyes. He hadn't been scared for himself; he'd been scared for Katsuki. It rattled him in ways he couldn’t understand. 

He had been guilty eversince he asked Deku to kill himself when just hours later after he said that Deku saved him from getting kidnapped. He didn’t need saving—he didn’t want saving. But that guilt had eaten at him, merging with the anger he already struggled to control. So he had ignored him. 

He shifted uncomfortably in the stiff chair as his therapist droned on about his rut. She was trying to make sense of his aggression, linking it to his alpha hormones. He hated when she brought that up. It wasn’t about his rut, or the pheromones, or any of that crap. It was about how everything had spiraled out of control. Why couldn’t anyone see that? 

Noticing his discomfort, she shifted tactics. "I think you should join a club during the summer, vacation" she said, her voice calm but direct. "My son, Riku, also goes there. It's not just about keeping busy; it’s about channeling that energy of yours into something productive. You might even make some friends, Bakugo." 

Katsuki scoffed. Friends? He didn’t need friends. And a club? What kind of club could possibly help him? He opened his mouth to refuse, but something about the way she framed it made him pause. "Activities to control his anger," she had said. Could something like that really work? 

The thought of spending an entire summer cooped up in his room, stewing in his own rage, didn’t exactly appeal to him either. And the last thing he needed was to feel more out of control than he already did. 

"Fine," he muttered, not looking at her. "But I’m not going to be stuck with some weak losers." 

She smiled, though he didn’t see it. "I’m sure you’ll find a way to make it work." 

Katsuki left the office feeling more uncertain than ever. The guilt, the anger, the confusion about Deku and everything else—it wasn’t going away. Maybe this club would help. Or maybe it was just another waste of time. 

But as he shoved his hands into his pockets and headed home, something in the back of his mind whispered that it might just be worth a shot.

___________________________________________________ 

Katsuki had a scowl permanently plastered on his face as he trudged to the address on the crumpled paper his therapist had given him. His therapist’s voice still echoed in his head. “This will be good for a newly presented alpha like you, Bakugo. Help you control those negative emotions.” 

He scoffed. Control? Yeah, right. He didn’t need any of this crap. A club, sure, but maybe something like martial arts or boxing—*something useful*. The last thing he needed was to waste time with a bunch of weaklings. 

When he finally arrived at the address, he stopped dead in his tracks, his mouth slightly open. The sign on the building in front of him read, " Musutafu Babysitting Club and Childcare.” 

What the hell? 

This had to be a mistake. No way this was the place. He checked the address again. It was right. 

Katsuki pushed the door open and stepped inside. The sound of laughter and babbling filled the air, and the sight of toddlers and infants running around greeted him. Toys were scattered across the floor, and the walls were covered in colorful posters. He wrinkled his nose at the smell of baby wipes and disinfectant. 

“Kacchan?” 

That voice. Katsuki’s blood boiled immediately as he turned his head and saw none other than Izuku Midoriya crouched on the floor, wiping the nose of a toddler. 

“Deku?!” Katsuki growled. “What the hell are you doing here?!” 

Izuku blinked in surprise, standing up. “Kacchan? You’re… here for the club too?” 

Katsuki’s fists clenched. This couldn’t be real. Out of all the people in the world, Deku was here? 

Before Izuku could respond, a sleepy-looking man shuffled out from the back. His eyes barely open, he yawned and scratched his head. 

“You Bakugo?” the man asked, his voice tired and uninterested. 

Katsuki glared at him. “Who the hell are you?” 

“Aizawa,” the man muttered. “I run this place. Midoriya’s been the only one here for a while. You’re the new member.” 

Katsuki’s eyes widened. “No. Fucking. Way.” He turned toward the door, ready to bolt, but Aizawa held out a folded piece of paper. 

“I’ve got a letter from your therapist,” Aizawa said, handing it to him. 

Katsuki snatched it, eyes scanning the familiar handwriting: 

This club is a prescription for Bakugo Katsuki to help with his emotional control. If he tries to leave, notify his mother immediately. 

His heart sank. *His mother.* 

Aizawa leaned against the doorframe, yawning. “She also said if you refuse, I should give her a call. Besides, I need to head out today, and Midoriya could use the help with the pups.” 

Katsuki ground his teeth. If his old hag got wind of him trying to bail, he’d never hear the end of it. 

“Fine,” he snapped, stuffing the letter into his pocket. “But don’t expect me to like this.” 

Aizawa gave a half-hearted shrug. “Whatever. Just help Midoriya while I’m gone.” 

With that, Aizawa shuffled out the door, leaving Katsuki standing there, fuming. Izuku gave him a nervous smile. 

“It’s not so bad, Kacchan,” he said softly. “The pups are really sweet once you get to know them.” 

Katsuki shot him a glare. “Shut up, Deku.” He stalked off to a corner of the room, sitting down with a huff, his arms crossed over his chest. 

Toddlers ran around in a chaotic mess. Mahoro and Katsuma, two siblings, were chasing each other in circles. Eri was quietly playing with her bunny, while Kota built a tower of blocks. In the corner, in a small playpen, a baby—the therapist’s kid, Riku—was gurgling and staring at the ceiling. 

Damn it. Katsuki had thought the therapist’s kid would be a teenager, like him. Instead, he was an infant. 

Katsuki slumped further into the corner, glaring at everything around him. This was going to be a long, boring day. 

Katsuki was doing his best to ignore the chaos unfolding in front of him. The pups were running around, screaming and laughing like they didn’t have a care in the world. He slouched deeper into his corner, arms crossed, watching Deku fuss over the infant in the playpen. "Good," he thought. "Let Deku handle the brats." The less he had to deal with them, the better. 

It wasn’t long, though, before the other pups started to notice him. Mahoro, the loudest of the bunch, approached him first, pulling on his arm. “Come play with me!” she demanded, her small hands tugging at his sleeve. 

Katsuki scowled and yanked his arm away. “Piss off, brat.” 

But Mahoro wasn’t deterred. She kept pulling at him, whining until the other kids—Katsuma, Kota, and even Eri—gathered around, all staring up at him with wide, curious eyes. They were bombarding him with questions. 

“Why do you swear so much?” 

“Are you Izu-ni’s friend?” 

“Why don’t you smile?” 

The irritation bubbled up inside Katsuki until it exploded. He stood up, towering over them, and shouted, “Shut up and leave me alone!” 

The kids all jumped, eyes wide in fear, before scattering in different directions like frightened animals. Mahoro, who had been so insistent just moments ago, ran back to Izuku and hid behind him. 

Katsuki rolled his eyes, thinking it was over. But then he heard a low growl, and when he turned, he saw something that stopped him in his tracks. 

Deku was glaring at him, his eyes sharp and—angry? His lips were drawn back slightly, a growl vibrating in his throat. 

Katsuki blinked. Deku? Growling? 

“What the hell is your problem, Kacchan?” Izuku’s voice was low, controlled. “Why are you acting like this?” 

Katsuki snorted, though his chest tightened in confusion. “I’m acting like *this*? You’re the one who’s been acting all high and mighty, Deku. Growling at me? What, you think you’re better than me now?” 

Izuku didn’t back down. “You shouldn’t have shouted at the pups. And you shouldn’t keep treating me like that either.” 

Katsuki’s anger flared again, burning through the confusion. “Don’t act like you’re some big shot, Deku. You didn’t growl at those guys who were molesting you, but you think you can challenge me? If you’d fought back like a real man, I wouldn’t have had to get involved in the first place. Because of you, I got into that fight, and now I’m stuck in this shitty club as part of my therapy!” 

The room fell into a tense silence. The pups had stopped what they were doing, watching the confrontation unfold with wide eyes. 

Katsuki’s sharp words seemed to cut deeper than expected. He saw Izuku’s eyes widen, his lips trembling as tears filled his eyes. 

“K-Kacchan…” Izuku whispered, his voice breaking. “You… You’re still treating me like I’m nothing…” 

Katsuki huffed, crossing his arms. “What? You gonna cry again, you damn crybaby? A baby like you can’t take care of a bunch of brats. You’re pathetic.” 

The words stung like poison, and Izuku’s tears started to fall, but before Katsuki could say anything else, he felt something small collide with his leg. 

Mahoro had thrown herself at him, tiny fists pounding weakly against his knees. “You’re mean!” she shouted, her voice trembling with rage. “You’re a monster!” 

Katsuma joined her, grabbing onto his other leg. “Yeah! We hate you!” 

Even Kota and Eri got in on it, hitting him with all the strength their little hands could muster. “We hate Kacchan!” they all yelled in unison. 

Katsuki gritted his teeth, swatting them away like flies. “Tch. Whatever. You brats don’t scare me.” 

But the kids didn’t back down. Mahoro pulled at his pants, pulling them down to reveal his underwear and Eri smacked him with her stuffed bunny. 

“Let’s kill him!” Katsuma declared, his face scrunched up in determination. Kota kicked his balls and a pained noise left his lips. 

“Hey!” Izuku rushed over, grabbing Kota and pulling him back. “Don’t say that! Kacchan’s not a monster.” 

The kids all froze at Izuku’s words, glaring up at Katsuki with mistrust. 

“We hate him,” Mahoro muttered. 

Izuku shook his head, wiping his tears quickly and trying to smile. “No, you don’t. He just… doesn’t know how to show he cares. But he’s not a monster.” 

Katsuki rolled his eyes, leaning against the wall with a scowl. The pups didn’t seem to care about his presence anymore. They turned back to their games, completely ignoring him. 

And for the first time in a long while, Katsuki didn’t know what to say. So he headed towards the kitchen and made some porridge as Aizawa had instructed before leaving. He brought the food out and placed the bowl down. Katsuki sat back, watching as Izuku effortlessly handled the babies, feeding them spoonfuls of porridge with a gentle smile on his face. It was almost ridiculous how easily the kids had gone from hating him to happily eating from Izuku’s hand, as if the earlier chaos had never happened. 

Kota, who had been the most vocal about his distrust, hesitated for a moment before letting Izuku feed him. Izuku took a spoonful of the porridge and ate. "See?" Izuku said softly. "Kacchan didn't poison the food." 

Katsuki rolled his eyes but didn’t argue. He had followed Aizawa's instructions, making the porridge exactly as he was told. Still, seeing Izuku feed the babies one by one, he couldn’t help but feel a pang of guilt. 

"Maybe it was all my fault," he thought, watching Deku’s movements. He had treated Deku horribly, and now, seeing him like this—with the babies all gathered around him, trusting him—it hit Katsuki in a way he wasn’t ready for. The sight reminded him of a mama bird feeding her chicks, all huddled close, eager for the next spoonful. 

Katsuki sighed and dug into his own porridge, swallowing the knot of guilt that had lodged itself in his throat. Tch. He’d never let himself be seen like that. Caring for brats wasn’t his style. 

After lunch, Izuku wiped the kids' faces with gentle hands, and soon it was story time. Katsuki groaned inwardly when Izuku handed him a children's book, brightly colored and filled with idiotic-looking animals. 

“Kacchan, could you read them a story?” Izuku asked, his voice soft but hopeful. 

Katsuki sneered at the book, flipping through the pages with disdain. “This is stupid,” he muttered, but seeing the babies’ expectant eyes on him, he sighed and settled down on the floor with them, opening the book to the first page. 

He read with as little enthusiasm as possible, his voice gruff and flat, but the kids didn’t seem to mind. They were entranced by the pictures and the story, leaning into Izuku as they listened. 

After the book was finished, Izuku gathered the babies for naptime, singing a lullaby in a soft voice that Katsuki hadn’t heard in years. The sound was strangely soothing, and as the babies cuddled up around Izuku, their eyelids fluttering shut, Katsuki felt his own body relax. 

Before he knew it, he had drifted off to sleep, the warmth of the room and the soft lull of Izuku’s voice pulling him under. 

When Katsuki woke up, the room was quiet. The babies were all curled up, sleeping soundly next to Izuku, who had dozed off sitting up, his head drooping slightly. His breath was even and calm, his face peaceful in sleep. 

Katsuki rubbed his eyes, stretching slightly as he took in the sight before him. All the kids had naturally gravitated toward Izuku, snuggling into him like he was their safety net. Eri had her head resting on his lap, while Mahoro clutched one of his hands in her sleep. 

For a moment, Katsuki just watched them. There was something about the way Izuku handled the kids, the way he instinctively knew how to care for them, that made Katsuki's chest tighten. 

"Maybe Deku will present as an omega," he thought suddenly, the idea hitting him out of nowhere. He was good with pups, nurturing in a way that Katsuki would never be. The sight of Deku surrounded by the little ones, caring for them like it was second nature, only fueled that thought. 

Katsuki’s inner alpha rumbled at the idea, something primal and possessive stirring inside him. He quickly shook his head, pushing the thought away. "Stupid. Why the hell am I thinking about that?" 

But as he looked at Izuku again, still fast asleep with the kids piled around him, Katsuki couldn’t help but feel a strange sense of admiration. For all the things he hated about Deku—his softness, his inability to fight back—there was something undeniable about how good he was with people, how he always seemed to know how to calm things down. 

Katsuki clenched his fists, turning his gaze away. He couldn’t let himself think like that. He wasn’t here to admire Deku. He was here to deal with his anger, to get through this stupid therapy, and get back to his life. 

But as he sat there, surrounded by the quiet, Katsuki couldn’t shake the guilt gnawing at him again. Maybe… maybe Deku wasn’t as pathetic as he’d always made him out to be. And maybe, just maybe, Katsuki had been wrong about a lot of things. 

The thought only made his chest tighten more. The door creaked open, and Aizawa stepped in, looking just as sleepy as ever. His eyes scanned the room briefly before Eri, who had just woken up, scrambled to her feet and rushed over to him. She wrapped her little arms around his leg, and Aizawa picked her up with ease, a small, almost imperceptible smile tugging at his lips. 

"Hey, Eri," he murmured softly, patting her head. 

Izuku stirred, blinking his eyes open as the room came back to life. The babies were immediately drawn to the bags Aizawa carried, filled with new toys and books. Their excitement filled the space as they eagerly tore open the packages, laughing and chattering among themselves. 

Katsuki watched from a distance, arms crossed, trying to ignore the warm, familial atmosphere that had settled over the room. "Tch, stupid brats," he thought again, but there was a hollowness in the insult this time. 

It wasn’t long before the parents began arriving to pick up their kids. One by one, the babies said their goodbyes, some waving with sleepy grins, others already half-asleep in their parents' arms. Katsuki remained quiet, helping to gather the remaining toys and books with a scowl, but his heart wasn't in it. 

Once the last of the pups had gone home, Aizawa looked over at Katsuki. “You’re on clean-up duty,” he said, his tone casual but firm. 

Katsuki clicked his tongue in annoyance, but he didn’t argue. He grabbed a broom and started sweeping up the crumbs and scattered toys from the day. To his surprise, Izuku stayed behind to help. He didn’t say a word, didn’t even look Katsuki’s way, but he silently gathered the rest of the toys and wiped down the tables. 

The silence between them was heavy, almost suffocating. Katsuki stole a glance at Izuku every now and then, but Deku’s focus never wavered from his tasks. It was as if Katsuki wasn’t even there, and that fact gnawed at him, though he refused to admit it. 

When everything was finally cleaned up and Aizawa locked the door behind them, Izuku gave a small wave and muttered a quiet, “Goodbye, Sensei,” before heading off. 

Katsuki shoved his hands into his pockets and followed a few steps behind. They walked in silence, both heading in the same direction, but neither of them said a word. The tension was palpable, though neither seemed willing to break it. 

The streets were quiet, the sun dipping low in the sky, casting long shadows over the pavement. Katsuki’s mind raced, filled with conflicting thoughts he couldn’t shake off. Guilt, anger, and something else—something he didn’t want to name—stirred within him as he walked just ahead of Izuku. 

"Damn it," he thought, gritting his teeth. "Why does it have to be like this?" 

But still, he said nothing. Neither did Izuku. And so they walked, side by side yet worlds apart, all the way home.

Chapter Text

It had been almost a week since Katsuki started coming to the babysitting club, and though he still felt annoyed every time he walked through the door, there was no denying that he was starting to get used to the place. The brats, for one, weren’t scared of him anymore. In fact, they seemed to enjoy getting on his nerves. They loved it when he got angry, laughing and giggling as they pretended to "slay the monster"—which, apparently, he made a far better one than Deku ever could. 

Katsuki would never admit it, but there was something strangely satisfying about the routine. Sure, the babies were annoying as hell, but there was a weird comfort in the way they pestered him, almost like they expected him to always be there. And while Izuku was good with kids—gentle and patient, as Katsuki begrudgingly noticed—he was also clumsy as hell. Always tripping over toys, knocking things over, and making dumb mistakes. 

But Katsuki? He was good at everything. He learned fast, whether it was cooking meals the pups loved or, to his horror, becoming an expert at changing Riku's diapers. He hated how proud of himself he secretly felt when Mahoro clung to his leg, asking him to play, or when Kota started repeating some of the things Katsuki said… though, that one caused some trouble. 

Aizawa had been outraged when he heard Kota repeat a string of curse words Katsuki had muttered under his breath. "We don’t need these kids learning any bad habits from you," Aizawa had said, practically deadpan, before setting up a swear jar in the corner of the room. Every time Katsuki slipped up, he had to drop a coin in the jar. 

So, Katsuki had to learn to control himself, something that hadn’t come easy. His vocabulary now included gems like "frog" in place of the f-word, and while he was still working on a replacement for “ass,” he figured he was doing okay. Better than he expected, at least. 

Still, it wasn’t like he liked being here. But he could see now why his therapist had sent him to this weird babysitting club. As much as he hated to admit it, the brats were starting to grow on him. It was impossible to ignore the way the milky scent of the pups calmed something deep inside of him. His alpha instincts, the same ones that used to make him so angry and volatile, were now slowly shifting toward something else—something more protective. 

Katsuki found himself growing less angry as the days passed. Being around the pups, even when they were driving him up the wall, seemed to chip away at the constant rage that had always been with him. But there was still something gnawing at him—something he couldn’t ignore no matter how much time he spent with the brats. 

It was Deku. 

The nerd wasn’t talking to him. Not a single word unless it was about the pups or something related to the club. And that made Katsuki feel something he wasn’t used to feeling—guilt. A heavy, uncomfortable weight in his chest that never really went away. 

He knew he’d messed up. He’d known that since the fight, since Deku had confronted him with those words that had stopped him dead in his tracks. "Why are you so angry, Kacchan? You bully me too." It was like getting hit by a truck, and he hadn’t been able to shake the feeling since. The fact that Deku had tried to protect him after he told him to kill himself? It only made the guilt worse. 

And now, here they were, stuck together in this dumb club. The pups adored Deku, of course. He was soft, gentle, and always full of endless patience. They called him "Izu-ni-chan" with so much affection that it made Katsuki feel like he was witnessing something private, something he didn’t belong in. 

Katsuki, on the other hand, had a different approach. He was strict, harsh, and didn’t hesitate to shout when the pups got too hyper. Sometimes he’d even give them a light smack on the head if they were being particularly annoying. The pups would pout and claim they *hated* him for being mean to "their Izu-ni-chan," but Katsuki knew better. Despite their protests, they were getting attached to him too. He could feel it in the way they gravitated toward him, even when he was in a bad mood. 

He even started using the babies as dumbbells during his workouts, much to the pups’ delight. They loved climbing on his back when he did pushups, giggling and clinging to him like little monkeys. He’d roll his eyes, but a small part of him liked that they weren’t scared of him anymore. 

Of course, Deku would scold him every time. "Kacchan, you can’t do that! You could hurt them!" Deku’s voice had a stern edge that Katsuki wasn’t used to hearing. It was weird—seeing Deku like this. Brave. Protective. As if these pups were his responsibility. It reminded Katsuki of something he’d heard once, about how omegas could go feral to protect their young. 

But Deku hadn’t presented yet. Still, there was something about the way he cared for the pups that made Katsuki think… maybe he would. Maybe he was born to be an omega, the way he naturally fell into that nurturing role. 

Katsuki’s inner alpha rumbled at the thought, unsettling him. He wasn’t sure what to do with that feeling, so he pushed it aside, focusing instead on the pups and their endless energy.

Chapter Text

One day, a group of new volunteers joined the babysitting club—high school kids who seemed way too energetic for Katsuki’s liking. There was Mirio, a tall, bright blonde who instantly lit up the room with his big, stupid smile. The moment the pups laid eyes on him, they all rushed toward him like he was some kind of hero. Within minutes, they were hanging off his arms, laughing as he lifted them with ease, his infectious energy taking over the entire club. 

Then there was Nejire, her long blue hair flowing behind her as she twirled around, captivating the kids with her sweet voice and endless curiosity. The brats were absolutely mesmerized by her, following her around like she was some kind of fairy princess. Mahoro couldn’t stop staring at her, eyes wide with admiration. 

And then there was Tamaki, a quiet, dark-haired guy who spent the whole day sitting nervously in a corner, barely saying a word. He seemed uncomfortable around the pups, flinching whenever one of them got too close, but somehow the pups still found him endearing. 

Katsuki’s alpha instinct flared with irritation. 

These three had only been here for a few hours, and already they were stealing all the attention—*his* attention. The brats didn’t even bother pestering him for once, too busy with Mirio and Nejire. Even Deku, who was always hovering around the pups, had been drawn into their orbit. Katsuki watched as Izuku laughed along with Mirio, helping him lift the toddlers into the air as they squealed in delight. 

Katsuki’s jaw clenched. His fists tightened at his sides. 

His alpha was clearly disappointed. Annoyed, even. It wasn’t just about the pups flocking to Mirio—it was about Izuku too. Deku hadn’t smiled like that in front of him for days. He was barely acknowledging Katsuki’s existence, but now, here he was, beaming at Mirio like the guy was his new best friend. 

It shouldn’t have bothered him. It *shouldn’t* have. But it did. 

The pups were all over the place, running around and giggling as they played with their new favorite people. Eri and Kota were clinging to Mirio, while Mahoro followed Nejire around like a shadow. Even Tamaki had somehow caught the attention of Katsuma and Riku, his nervous energy making them curious about him. 

Katsuki sulked in his corner, scowling at the scene. This was supposed to be his territory. *His* club. He had finally started to settle into the rhythm of things, and now these high schoolers waltzed in and turned everything upside down. 

The worst part was how easily Izuku fit in with them. Like he had known them for years. Watching him laugh and joke with Mirio and Nejire—Katsuki hated it. Hated how left out he felt. Hated how his alpha instincts rumbled with dissatisfaction, demanding attention he wasn’t getting. 

The day dragged on, with Katsuki simmering in his frustration. Every time Mirio threw one of the kids in the air or Nejire twirled around with Eri, Katsuki’s irritation grew. He’d had enough of being ignored. 

When the day finally ended and the three high schoolers left, the brats were all buzzing with excitement, begging Aizawa to let Mirio and the others come back. 

“Maybe,” Aizawa said, scratching his head, clearly exhausted by the pups’ energy. “We’ll see.” 

Katsuki scoffed, crossing his arms as the brats surrounded him with their newfound obsession for Mirio. Even when he tried to get back to his usual routine, the pups kept comparing him to the blonde. 

“Katsu-ni-chan, can you lift us like Mirio did?” Mahoro asked, tugging on his sleeve. 

“Katsu-ni-chan, why don’t you smile like Mirio?” Kota added, giving him a skeptical look. 

Katsuki’s eye twitched. “Shut up! I’m not here to smile like that dumbass!” He growled, stomping away from the group. 

But deep down, he knew the real reason for his anger. It wasn’t just about Mirio. It was the fact that Izuku still wasn’t talking to him. Izuku had smiled for Mirio. Laughed with him. And yet, Katsuki couldn’t get more than a few words out of him. 

It gnawed at him, that guilt resurfacing again. 

As the day came to an end and the brats went home, Katsuki glanced at Izuku out of the corner of his eye. Deku was packing up some of the toys, his expression calm and content, as if today hadn’t been a big deal at all. 

Katsuki clenched his fists, swallowing down the surge of emotions that threatened to rise. He couldn’t stand this anymore. Something had to change. But for now, he stayed quiet, trying to ignore the way his alpha instincts screamed for Deku’s attention. 

He just hoped things would get better soon, or else he didn’t know how much longer he could stand being ignored.

Chapter Text

It was one of those rare days when Aizawa had to step out for some work, leaving Katsuki and Izuku in charge of the daycare. The pups were playing quietly, blissfully unaware of the chaos about to unfold. 

Katsuki leaned against the wall, watching Deku hum some tune while wiping down the tables. The day had been uneventful, and it was almost time for lunch. That’s when the door slammed open. 

In strode four figures, thugs Katsuki instantly recognized: Muscular, Chisaki, Dabi, and Shigaraki. 

“What the hell…?” Katsuki muttered, his eyes narrowing. These bastards had tried kidnapping him a few months ago. He wasn’t about to let them waltz in here and start trouble again. 

Muscular cracked his knuckles, his grin wide as he zeroed in on Kota. “Looks like we found some prime targets.” 

Before anyone could react, Muscular grabbed Kota, hoisting him up like a ragdoll. Meanwhile, Chisaki, with his usual calm malice, reached for Eri, snatching her up with ease. 

The pups screamed, and Izuku’s eyes went wide. “Let them go!” Without hesitation, he grabbed the nearest thing—an empty sippy cup—and hurled it at Muscular’s head. 

Muscular flinched, though not from pain—more from confusion. “What the—? A sippy cup?” 

Deku wasn’t done. He quickly followed it up by throwing anything he could get his hands on: a stack of picture books, a plastic toy, a tiny chair, even diapers. “Get away from my pups!” 

“You’ve gotta be kidding me…” Muscular dodged a plastic train, but Deku’s relentless barrage continued. 

Meanwhile, Shigaraki smirked, stepping forward. “Stay out of this, unless you want—" 

Before he could finish, Katsuki was already on him. “Oh, hell no!” Katsuki tackled Shigaraki, landing a solid punch to his jaw. “You think you can just waltz in here after last time? You nut-sac-faced man!” He remembered all too well how Shigaraki and Dabi had tried to kidnap him. Not again. 

Dabi stepped in, clicking his tongue. "Never expected you’d be here, Bakugo. How about we finish what we started?” 

Katsuki smirked. “I was hoping you’d say that.” Without missing a beat, he swung a roundhouse kick, sending Dabi stumbling backward into a bookshelf. Toys and books rained down on him. 

The fight quickly spiraled into chaos. Deku was still throwing anything he could get his hands on, dodging Muscular’s attempts to grab him. Chisaki tried to keep hold of Eri, but she bit his arm, forcing him to drop her with a yelp. Eri scrambled to Izuku, hiding behind him as he continued to fend off the thugs with sheer determination and makeshift weapons. 

The commotion was loud enough that it attracted the attention of the neighbor, Mr. Hisashi Yamada. Peeking out from his window, he quickly dialed the police. “Uh… yeah, I think there’s a bit of a situation next door. Better send someone fast.” 

Within minutes, Inspector Yagi Toshinori and Enji Todoroki, arrived at the scene. The two officers kicked the door open just as Katsuki landed another punch on Shigaraki, knocking him out cold. Muscular was covered in juice boxes and toys, looking utterly confused as to how he had lost to Deku’s bizarre weapon choices. Dabi, still buried under a pile of books, groaned in pain. Enji grabbed him by collar and cuffed him. "You come with me. Runaway child of mine." 

Yagi let out a low whistle as he surveyed the scene. “Well, well. Looks like you two handled things here pretty well.” He smiled warmly at Izuku. “Impressive, young man. You really know how to protect these pups.” 

Izuku, flushed from exertion and adrenaline, blinked. “Uh… thank you, sir.” 

“And you,” Yagi turned to Katsuki, “it’s good to see you using your strength to protect rather than brawl. You’ve come a long way, Bakugo.” 

Katsuki just grunted, crossing his arms. “Tch. Whatever.” 

Enji cuffed the dazed criminals and led them out of the daycare, Shigaraki shooting a glare at Katsuki as he was dragged away. “This isn’t over,” he muttered. 

“Yeah, yeah,” Katsuki waved him off. “See you in jail, loser.” 

Once the cops were gone, the pups gathered around Izuku and Katsuki, still shaken but safe. That’s when Katsuki noticed something—Izuku was cradling his hand, blood dripping from a gash across his knuckles. 

“Oi, Deku, what the hell?” Katsuki growled, grabbing his arm to inspect the injury. “You’re hurt.” 

“I-I’m fine, Kacchan, it’s just a scratch—” 

“Shut up,” Katsuki snapped, grabbing the first-aid kit from the shelf. He pulled out some bandages and antiseptic, roughly cleaning Izuku’s hand. “What were you thinking, going up against those guys without a plan? You could’ve gotten yourself killed.” 

Izuku winced but said nothing, letting Katsuki patch him up. 

“Next time, don’t fight unless you’ve got the skills to back it up,” Katsuki continued, his voice harsh but laced with concern. “You’re too soft, Deku. You need techniques. Planning.” 

Izuku blinked, looking up at him. “A-And how do you suppose I do that?” 

Katsuki finished wrapping the bandage around his hand and stood up, a determined glint in his eyes. “I’ll teach you—and all these brats too. Starting tomorrow, I’m giving everyone here self-defense lessons.” 

The pups, who had been quietly watching, perked up at this. “Self-defense? Katsu-ni-chan’s gonna teach us to fight?” 

Katsuki smirked, cracking his knuckles. “Damn right. No one’s gonna steal you guys again. Not on my watch.” 

Izuku, despite the chaos of the day, couldn’t help but smile a little. “Thank you, Kacchan.” 

“Shut up, nerd,” Katsuki muttered, though his tone was softer than usual. “Just get ready for tomorrow. You’re all gonna need it.”

Chapter Text

Katsuki gathered the pups at the babysitting club, eager to teach them some self-defense basics. They stood in a clumsily, looking up at him with big, eager eyes, each of them trying their best to strike “tough” poses. Izuku watched from the side, feeding baby Riku milk with a bottle, absolutely charmed by their attempts to look fierce and focused. Kota and Mahoro were excitedly kicking Katsuki and punching him. 

"Alright, listen up, brats," Katsuki announced, folding his arms. "We’re gonna start with the basics: staying safe. I want discipline. Everyone line up!" The toddlers made a clumsy line. Katsuki continued, "So first rule—don’t talk to strangers. Don’t take anything from them, no matter what they say." 

The pups nodded, their faces scrunched up in concentration. Katsuki went on, "If someone grabs you, scream as loud as you can. And if anyone tries to cover your mouth, bite down hard and don’t let go." 

Kota, arms crossed like a little tough guy, piped up, “This is boring. Show us how to actually fight!” 

Katsuki rolled his eyes but smirked. "Fine. Deku!" he called over to Izuku, who looked up, surprised. "You’re my assistant for this." 

Izuku’s eyes sparkled as he put the baby back on his cradle and joined Katsuki in front of the kids. He looked almost as excited as they were. 

"Alright, nerd," Katsuki said with a grin. "We’re gonna start with blocking punches and kicks." 

Katsuki demonstrated a series of simple moves, showing Izuku how to block different types of attacks. To his surprise, Izuku was catching on quickly. 

"Good instincts, Deku," he muttered approvingly, making Izuku blush. 

Next, Katsuki taught the kids how to target vital points in self-defense: "Eyes, ears, stomach. If someone’s trying to grab you, aim for one of those." 

Kota raised his hand and proudly announced, “I’m really at kicking balls!” 

Katsuki groaned, instantly remembering when the little menace had actually kicked him in that very spot a while back. He shot Kota a look, but the pup only snickered. 

Moving on, Katsuki showed Izuku how to break free if someone grabbed him from behind. He wrapped his arms around Izuku's waist to demonstrate. “Alright, Deku, follow my lead. Here’s how to twist out of a hold like this—” 

But as he held Izuku close, Katsuki’s voice faded for a second. His face grew a little warm, and his heart stuttered. Something about this moment made him pause. Izuku seemed to notice too, glancing back with wide eyes, his cheeks going red. He was looking like a strawberry with his freckled red cheeks and green hair. Katsuki wanted a bite of the strawberry. 

Katsuki quickly refocused. Clearing his throat, he went on with the demonstration. The pups clapped when Izuku fred himself from Katsuki’s grip. He moved on to demonstrate how to escape when pinned down. He placed Izuku on the mat, pinning him down gently but firmly with both hands. 

"Now, Deku," he instructed, "when someone’s got you pinned, you need to—" 

But then he stopped again, staring down at Izuku. For a split second, he felt his heartbeat pick up, his chest tightening at the sight of Izuku's bright green eyes staring up at him. Katsuki’s face flushed as he realized just how close they were, his alpha instincts stirring in a way that made him feel uncharacteristically flustered. 

Then, a voice broke through the moment. 

"Uh, what exactly are you two doing?" Aizawa-sensei’s voice came from the doorway, sounding distinctly unimpressed. 

Katsuki instantly jumped up, practically yanking Izuku to his feet. They both turned to Aizawa, faces red with embarrassment. 

The pups chimed in, “Katsu-ni-chan was teaching us how to fight!” 

"You two were fighting in front of........"

Befor Aizawa could complete, Izuku quickly added, “No! We were teaching them. Just... just self-defense!” He rubbed the back of his head, a nervous laugh escaping him. 

Aizawa sighed, folding his arms. "Self-defense, huh? Next time, let me know first." 

Despite his tone, Aizawa joined them on the mat, showing the kids a few self-defense techniques of his own, bringing the lesson back on track. 

Katsuki tried to focus, but he kept glancing over at Izuku, wondering why he’d felt so flustered before. He shook his head, silently cursing his own alpha. What was wrong with him? Why did just looking at Izuku make him feel so... well, warm? 

But as the kids laughed and practiced their moves, Katsuki decided that maybe—just maybe—this was one of those things he didn’t mind too much after all.

Chapter Text

It was a typical day at the daycare, the pups running around in their usual chaotic way. They didn't show even a bit if tiredness after Katsuki’s self defence training. 

Izuku was braiding Eri's hair and Mahoro was putting some colourful hairclips on Katsuki's porcupine head. "Tada! How does he look?" Mahoro asked after she finished her work. Izuku glanced at Katsuki. "Very handsome!" Izuku replied as a blushing Katsuki pinched baby Riku's chubby cheek and chomped on it. The baby didn't express any pain and was giggling. 

Izuku laughed and took the baby away from Katsuki. "Kacchan, when we were pups, you used to do that to me too." Katsuki tched in answer and took the hairclips off his hair, much to Mahoro's disspointment. 

"Ahhhh....... I worked so hard on that why did you take them off." She screamed pulling Katsuki’s pants to climb up his body like she always did. But unfortunately this time,  Katsuki’s pants came down. Izuku quickly looked away while the pups couldn't stop laughing. 

"His wee wee is big." Katsuma pointed out innocently. "Kacchan aren't you wearing an underwear? " Izuku screamed still facing the other way. The pups giggled even more. "He is wearing one. It has little bombs on it. Boom! Boom!" Mahoro shouted excitedly for no reason. Katsuki ran to the kitchen in embarrassment covering it with a mask of anger. 

Shitty brats! Shitty hairclips! Shitty bomb underwear! 

Katsuki took his anger out scrubbing a cast iron pan muttering a string of curses. Then made omelette which turned into scrambled eggs because he took out his anger on the poor eggs. 

"Die eggs! Die! Die! Die!" 

When he came out of the kitchen with lunch, the pups were looking terrified and Izuku was too embarrassed to even look at him. Mahoro approached him with teary eyes and apologised while Kota laughed once again replaying the scene in his mind. A glare from Katsuki was enough to send Kota into silence once again. They all had lunch in silence. 

After the lunch, it was nap time. Izuku set the futons while Katsuki busied himself in clearing the room. Katsuma, one of the more curious kids, tugged at Izuku’s shirt. “Hey, Izu-ni-chan,” he asked innocently, “where do babies come from?” 

Izuku froze, panic flashing across his face. How was he supposed to explain *that* to a bunch of kids? “Uh…well, you see, um—” 

“Babies?” Katsuki, who was nearby cleaning up toys, overheard the conversation and walked over casually. “It’s simple. When someone’s primary and secondary genders present, there’s stuff like sperm and eggs, and one needs to fuc... I mean have sex—” 

“K-Kacchan!” Izuku yelped, his face turning beet red as he frantically waved his arms. “Don’t tell them that!” 

Katsuki frowned, clearly confused. “What? It’s the truth.” 

Izuku jumped in front of him, forcing a nervous laugh. “N-no, no! Kacchan knows nothing about it. When parents pray to God, he gives them pups, and, um, the storks deliver them!” 

Katsuki stared at him, completely dumbfounded. The kids, however, seemed to accept the explanation without a second thought, their wide eyes full of wonder. “Ohhh, storks!” they chimed. 

For the rest of the day, Katsuki stayed uncharacteristically quiet. But as soon as the daycare closed and the last pup had left with their parents, he burst into laughter the moment they stepped outside. “Storks? Seriously, Deku?” 

Izuku blushed furiously, his face burning with embarrassment. “I panicked, okay?! They’re just kids!” 

Katsuki shook his head, still chuckling. “God, you’re such a nerd.” 

But there was no malice in his teasing, just a light-heartedness that made Izuku smile despite his embarrassment. "Don't tease me Kacchan I am not the one who wears Boom! Boom! underwears." 

Katsuki stilled. He closed his eyes and faced the other way. "I am sorry but that was so funny Kacchan!" Izuku burst into laughter. Katsuki looked at Izuku's face eyes scrunched up and a hand covering his mouth while he laughed and laughed and laughed. Katsuki chuckled. They laughed together, something they hadn’t done in a long time, and as the evening air settled around them, Katsuki’s laughter faded, leaving a softer expression on his face. 

He had always made Izuku cry. He was making Izuku laugh for once. Katsuki glanced at his smiling face. He noticed how Izuku's face was glowing from happiness. Katsuki wanted to see him like that, glowing with happiness forever. And he knew what he had to do.

Chapter Text

“Oi, Deku,” Katsuki said suddenly, his voice more serious now. “Come with me. There’s someplace I wanna show you.” 

Izuku blinked, curious. “Where?” 

“Just come on,” Katsuki said, walking ahead without further explanation. Izuku followed him, and they soon found themselves at the edge of a creek, the familiar spot where, as kids, they had once played. 

Katsuki stopped and pointed to the creek. “Remember this place? I fell in here once when we were pups.” 

Izuku stared at the water, the memory rushing back to him. “Yeah…I remember. I reached out to you to help, but…” His voice trailed off, and Katsuki clenched his fists at his sides. 

“I didn’t take your hand,” Katsuki finished for him, his voice thick with guilt. “I left you there, didn’t even look back. I was such a bastard to you.” 

Izuku looked at him, wide-eyed. Katsuki’s usually brash and confident demeanor was gone, replaced by something raw and vulnerable. “Kacchan…” 

“I’m sorry, De....Izuku,” Katsuki said, his voice low. “I’ve been carrying that guilt with me for years. I was so messed up, so angry back then. And now, every time I look at you… I feel like I owe you. I owe you so much for the way I treated you.” 

Izuku’s heart tightened. He’d never expected Katsuki to apologize, not like this. For a long moment, neither of them spoke, the only sound being the gentle flow of the creek. 

“Kacchan…” Izuku began softly. “I forgave you a long time ago. I know you’ve changed. You’re not that person anymore.” 

Katsuki looked at him, eyes searching his face for any sign of resentment, but there was none. Izuku’s smile was soft, forgiving. 

“I know it’s hard to let go of guilt,” Izuku continued, “but you don’t have to carry it anymore. I’m okay. We’re okay.” 

Katsuki nodded, swallowing the lump in his throat. “Thanks, Izuku.” 

They sat by the creek for a while, talking quietly, the conversation shifting to lighter things. Izuku admitted to Katsuki about the trauma he’d been through after being molested, explaining how working at the daycare with the pups had helped calm his mind. 

Katsuki, for once, didn’t interrupt. He listened, really listened, his alpha instincts flaring with protective anger at the thought of anyone hurting Izuku. “Those brats are cute,” he finally muttered when Izuku finished. 

Izuku laughed softly. “Kacchan never shows it.” 

“I don’t know how to show it, okay?” Katsuki grumbled. “ I try to do my best. I read a lot of books. I find ways to be good with them. I never half-ass anything, you know that.” 

Izuku’s smile grew. “You’ll be a really good sire one day, Kacchan.” 

Katsuki’s alpha practically purred at the compliment, his chest swelling with pride. But all he said was, “Yeah, well, we’ll see.” 

Izuku leaned back, staring at the sky. “School’s starting again in a few weeks. I’m gonna miss my babies.” 

Katsuki sighed. “Me too.” 

They sat in comfortable silence for a moment before Izuku broke it, his voice quieter now. “Kacchan, what do you want to do after middle school ends?” 

“UA,” Katsuki said immediately. “I’m going to UA High and then I’ll become a cop. Nothing less.” 

Izuku’s eyes widened. “Sugoi, Kacchan! That’s amazing.” 

Katsuki smirked, but there was a softness in his eyes. “What about you, Izuku? What are you gonna do?” 

Izuku hesitated, his smile faltering slightly. “I want to go to UA too, I want to study criminal psychology when I go to college, but…” 

“No buts,” Katsuki interrupted, his voice firm. “Don’t doubt yourself. You’re getting into UA. And when you do, we’ll compete in studies. I’m not gonna let you fall behind and I'm still gonna win.” 

Izuku’s heart warmed at the confidence Katsuki had in him. He smiled again, this time brighter. “Thank you, Kacchan.” 

Katsuki just shrugged, but there was a small, satisfied smile tugging at the corner of his lips. “Yeah, yeah. But criminal psychology? Seriously?” 

Izuku chuckled and looked away, "I want to become a special officer in crime branch. You know what I mean? Undercover investigations and all. But I don't know if I am fit for this job. I don’t even know how to protect myself. My mind went empty and I acted without a plan or thinking twice when the pups.... " 

"You are smart Izuku! " Izuku looked up to find red eyes staring at him. "Smarter than you think. It's completely normal to panic in situations like that. I think that is why you want to study criminal psychology, so that you will know what to do in such situations. Undercover missions huh? Sounds good. You know what if you learn how to fight you will be great. A badass fighter hiding behind an innocent baby face." 

"I don't have a baby face. " Izuku pouted. Katsuki chuckled pinching his cheek, "Oh you definitely have a baby face. Hey! I've got an idea. What about you train with me. I can teach you a thing or two about physical training and stuff." 

Izuku's face lit up. "Really Kacchan? Thank you!  Thank you! " Izuku pulled him into a hug. The hug was over within a few seconds but it kept repeating in Katsuki’s mind as they walked their way towards home. He kept thinking about it even after he reached home and they bid farewell. He kept thinking about it even during dinner. He kept thinking about it even he was lying on his bed waiting for sleep to embrace him. He kept thinking about it again and again.

Chapter Text

The daycare was bustling with the usual energy of pups playing and laughing, but Izuku wasn’t his usual bubbly self. Katsuma was the first to notice, tugging at Izuku’s shirt. “Izu-ni-chan, are you okay?” he asked, concern in his eyes. 

Izuku tried to smile, brushing off the worry. “Yes, I’m fine,” he said, but Katsuki could see the sweat starting to bead on his forehead. Izuku’s breathing was quickening, and his face was flushed a deep red. 

“Oi, nerd, you okay?” Katsuki stepped closer, narrowing his eyes. Izuku’s response was another weak “I’m fine,” but Katsuki wasn’t buying it. His hand shot up to feel Izuku’s forehead. It was burning hot. 

“Stop lying, you’ve got a fever,” Katsuki growled, his tone more worried than angry. 

Eri, who had been coloring nearby, stood up and walked over, her small face etched with concern. “You’re sick, Ni-chan.” 

But Katsuki suddenly realized it wasn’t just a fever. The scent hit him—a fresh, earthy smell, like the rain on a spring day. It was soft, sweet, and unmistakable. Izuku wasn’t sick. He was presenting. *He was going into heat.* 

Panic surged through Katsuki. This wasn’t supposed to happen here, especially not now. “Shit...” he muttered under his breath. 

“Kacchan! What’s happening to me?” Izuku whimpered, his voice trembling with fear and confusion. 

Katsuki knelt down, trying to keep his cool. “Nothing. Just… stay here for a bit. I’ll call Aizawa-sensei.” He made to stand, but Izuku grabbed his arm, pulling him back down. 

“No! Don’t leave me, Kacchan!” Izuku’s voice cracked, tears starting to well in his eyes. 

Katsuki froze, unsure what to do. But Kota, quick to understand something was wrong, jumped to his feet. “I’ll get Aizawa-sensei!” he shouted before running out of the room to find their teacher, who had been napping in the other room. 

“Kacchan…” Izuku whimpered again, curling in on himself as a painful cramp seized him. Katsuki clenched his jaw and took Izuku’s hand. “I’m right here, nerd. Just hang on.” 

Moments later, Aizawa arrived, his usually half-lidded eyes wide with concern. He quickly assessed the situation, glancing between Izuku and Katsuki. “Don’t tell me he’s going into heat.” 

Katsuki nodded grimly. Aizawa sighed and ran a hand through his hair. “We need to inform his mother. I’ll take care of that, but you need to get him home.” 

“I’ll take him,” Katsuki said immediately, his voice steady despite the storm of emotions swirling inside him. He carefully helped Izuku stand, his arm wrapped securely around him. 

“Is he gonna be okay?” Katsuma’s small voice piped up, trembling with fear. 

Katsuki forced a smile. “Yeah, he’s gonna be fine. Don’t worry.” 

Aizawa packed up Izuku’s bag and handed it to Katsuki. “I’ll let his mother know. Just get him home safely.” 

With that, Katsuki guided Izuku outside. At first, Izuku managed to walk, but halfway through the journey, his legs gave out, and Katsuki had no choice but to carry him on his back. People on the street stared, their eyes drawn to the unusual sight of the two boys, but Katsuki growled at anyone who dared to look too long. He wasn’t in the mood. 

When they finally reached Izuku’s house, Katsuki fumbled with the keys, pulling them from Izuku’s pocket before pushing the door open. He hurried inside and took Izuku to his bedroom, gently laying him down on the bed. Izuku’s breathing was uneven, his face flushed even deeper than before. 

“You need to make a nest,” Katsuki said, trying to recall everything he’d read. He grabbed every soft thing he could find—pillows, blankets, even some of Izuku’s hero-themed plushies—and arranged them in a comforting circle around him. Katsuki piled them trying to make a little nest. 

Izuku, despite his dazed state, seemed to instinctively know what to do. He burrowed into the nest, seeking comfort as his body shivered with the overwhelming sensations of his first heat. Katsuki went to the kitchen to get him something cold to drink. When he returned, he froze in the doorway. Izuku had stripped off his clothes, too warm and uncomfortable to stay dressed.

Katsuki turned red instantly, eyes darting away. “Oi, put your clothes back on!” he shouted, grabbing a blanket to cover Izuku. He brought the glass of juice, infront of Izuku’s lips so he could drink it. Izuku however, wasn’t interested in the juice. He whined, shaking his head. 

“Just drink it,” Katsuki scolded, trying to keep his cool. "You need to stay hydrated." Izuku obediently took a few sips, though he still whimpered in discomfort. 

Katsuki could feel his own alpha instincts roaring inside him, the scent of Izuku’s heat making it hard to stay composed. He needed to leave before he lost control, but the thought of leaving Izuku alone like this—vulnerable and scared—kept him rooted to the spot. 

“Kachan…” Izuku’s voice was soft, almost a whisper. “I feel so empty… Need Kachan… Want babies…” He was delirious, his body shaking with need. 

Katsuki’s face went scarlet. “What the fuck are you saying?!” he yelled in pure embarrassment. 

Izuku didn’t seem to hear him. His eyes were half-lidded, his hands reaching out. “Kachan… want to cuddle… Eri-chan… Kota-chan… Mahoro… Katsuma… baby Riku......wanna cuddle my babies …” His words were jumbled, a mix of longing and confusion. Tears spilled down his cheeks. “Kachan… need to hug.” 

Katsuki sighed heavily, running a hand through his hair. “Fine,” he muttered, climbing into the nest beside Izuku. Izuku immediately curled into him, his arms wrapping tightly around Katsuki as if he were the only thing keeping him grounded. 

The warmth of Izuku’s breath against his neck made Katsuki’s heart pound. He fought to keep his emotions in check, focusing on anything but the intoxicating scent filling the room. 

“Auntie Inko will be home soon,” Katsuki said, more to distract himself than anything else. 

“Mmm,” Izuku hummed, too out of it to respond properly. 

Finally, the doorbell rang. Katsuki practically leaped out of the bed, thanking every deity he could think of that Inko wasn’t late. He rushed to the door and let her in, relief washing over him as she hurried to her son’s side. 

“Thank you so much, Katsuki,” Inko said, her voice full of gratitude. 

Katsuki barely managed a nod before bolting out of the house, his heart still racing from everything that had just happened. His embarrassment only increased when he realised he had a nosebleed. 

Chapter Text

Katsuma's wide eyes looked up at Katsuki, his voice filled with concern. “Is Izu-ni-chan really sick?” 

Katsuki’s first instinct was to blurt out something blunt, like how Izuku was probably squirming and moaning in bed thinking about a knot right now—but he caught himself. He couldn’t exactly say that. Instead, he tried to sound casual. “No, he’s not sick. He’s… in heat.” 

“What’s heat?” Eri’s innocent voice chimed in, her head tilted in curiosity. 

Katsuki froze for a second. How do you explain this to kids? He remembered the last time he tried explaining where babies come from, and Izuku had scolded and teased him endlessly afterward. He had to tread carefully here. “Uh… it’s something that happens to omegas.” 

“Oh, omega!” Mahoro piped up. “My mama’s an omega, too. Sometimes she has a fever and stays away from us.” 

Katsuki nodded, relieved that Mahoro had saved him from giving a full-blown explanation. “Yeah, it’s not a disease. The nerd’s gonna be fine in a few days. Nothing to worry about.” 

Still, despite his words, a small knot of worry twisted in Katsuki’s chest. He knew heat wasn’t dangerous, but seeing Izuku so vulnerable made his alpha instincts go on high alert. 

“Hey!” Eri’s eyes lit up with an idea. “Let’s make cards to cheer him up! I bet he’ll feel better if he sees them!” 

The kids quickly got to work, grabbing paper and crayons, and Katsuki, despite himself, found he was roped into helping. Between cutting, pasting, writing, and coloring, Katsuki realized he was doing almost all of the work while the kids chattered away happily. 

By the end of the day, Katsuki had a small stack of “Get Well Soon” cards in hand. When daycare was over, he found himself heading toward Izuku’s apartment, the bag of cards feeling oddly heavy in his grip. 

Inko opened the door when he knocked, her usual warm smile softening her tired eyes. “Oh, Katsuki! Come in.” 

Katsuki didn’t waste time with pleasantries. “How’s the nerd doing right now?” he asked, straight to the point. 

Inko sighed, her expression worried but calm. “His heat is at its strongest right now. He’s having a hard time dealing with it, but there’s not much I can do to help him.” She didn’t sugarcoat it, and Katsuki appreciated that. “It was so sudden. I wasn’t expecting it at all. Thank you for taking care of him, Katsuki.” 

Katsuki rubbed the back of his neck, feeling a bit awkward under her gratitude. “Yeah, no problem. Just… it was all kind of unexpected.” 

Everyone had thought Izuku would be a beta like his mom, so this sudden development had caught everyone off guard. 

“The brats at the babysitting club made these for him,” Katsuki said, handing over the paper bag filled with cards. “Give them to him when he’s feeling better.” 

Inko’s smile returned, brighter this time as she took the bag. “I’m sure he’ll love them. Thank you, Katsuki.” 

Katsuki gave a quick nod, muttering something about needing to head out before he left. As he walked away, he couldn’t help but feel a mix of relief and lingering concern for the nerd tucked away in his room. 

Katsuki paced around his room, feeling a knot of frustration tightening in his chest. It had been days since he’d seen Izuku, and it felt strange, unsettling even. He never thought he’d miss the nerd so much, but with Izuku stuck in heat, Katsuki felt like something important was missing. Not seeing his clingy, annoying face was… lonely.

Chapter Text

“Katsuki!” Mitsuki called from the hallway, poking her head into his room. “Inko just called. She says Izuku’s heat is subsiding and invited us over for dinner. The kid wants to see you.” 

Katsuki's heart skipped a beat, though he played it cool. “Yeah, whatever. Let’s go.” 

When they arrived at the Midoriya household, Izuku was already waiting at the table, his face flushed a soft red and his eyes a little hazy from the lingering effects of the heat. He still had a mild fever, but the worst was over. Katsuki could feel his alpha instincts stir, noticing how vulnerable Izuku looked, and without a word, he sat down next to him. 

Izuku glanced up, his lips curling into a tired smile. “Kachan…” 

Katsuki huffed but didn’t push him away as he took over serving Izuku’s plate, making sure he had enough food. Izuku’s hands were trembling slightly, so Katsuki helped him eat too, holding the spoon steady. Both Inko and Mitsuki exchanged surprised glances, but they didn’t say anything, not wanting to interrupt the quiet moment between the two boys. 

Izuku, still a bit foggy, leaned against Katsuki, resting his head on his shoulder. “How are our pups?” he mumbled, his voice soft and clingy. 

Katsuki smirked, sensing an opportunity to tease him. “Oh, they don’t miss you at all. They’ve decided I’m better because I’m not a crybaby like you.” 

Izuku’s face immediately fell, his lower lip trembling. “But… but I…” His voice cracked, and his eyes welled up with tears. 

Katsuki cursed under his breath, realizing he’d taken it too far. “Oi, oi, calm down. I was just kidding, nerd. Of course, they miss you. They won’t stop asking when you’re coming back. And me—" He sighed, rubbing the back of his neck. “I want you back too. Those brats are annoying the hell out of me without you there to babysit them.” 

Izuku sniffled but managed a small smile. “Really?” 

“Yeah, really,” Katsuki muttered, still feeling a bit embarrassed by the whole situation. 

After dinner, as they were getting ready to leave, Izuku suddenly hugged Katsuki from behind. His arms wrapped tightly around Katsuki’s waist, and Katsuki stiffened, looking around to make sure no one saw. Luckily, both their moms were in the kitchen, and Katsuki allowed himself to relax, if only for a moment. 

Izuku's body was so warm. And his scent was divine even with the scent patch. A low purr escaped his lips. "Izuku....." 

"Ok we should leave now. Good bye!" Katsuki heard Mitsuki bidding farewell to Inko. He quickly worked to unwrap Izuku’s arms around him. "Kacchan? Are you leaving?" Izuku asked with a look of disspointment. "Yeah! Be a good boy and come back to your normal self. You're even more clingy when in heat." As both of their moms came close, Katsuki waved his hand, "See ya!" Inko took her heat-dazed son’s hand and made him wave a bye. 

When the Bakugos got home, Mitsuki wasted no time teasing Katsuki. “So, you’re his personal nurse now, huh? Serving him food, helping him eat, letting him cuddle you?” She grinned, poking at his pride. 

“Shut it, old hag,” Katsuki grumbled, his face heating up. “I was just helping him out, nothing more.” 

"Oh it looked as if you were courting him."

"Shut up hag! Just fuck that..." 

Katsuki and his mom continued while his dad tried to calm them down. After what seemed like an endless marathon of insults thrown at each other, his dad got some success. 

"Tch... whatever hag!" 

Katsuki left. But Mitsuki’s laughter followed him all the way up to his room.

Chapter Text

A few days later, Izuku returned to the babysitting club, his usual energy finally restored. The moment he stepped inside, the babies lit up, their squeals echoing around the room. Even the parents looked relieved to see him back. 

“Izu-nii-chan! You’re back!”

“We missed you so much!”

“Katsu-nii-chan has been a bad boy since you left!” 

The complaints came tumbling out, and Izuku couldn’t help but laugh. “Really? Is that true, Kacchan?” he asked, grinning at Katsuki. 

“Tch,” Katsuki scoffed, crossing his arms, but he didn’t deny it. 

“Katsu-nii-chan missed you so much! He was so grumpy. He even cried because you weren’t here!” Mahoro added with a mischievous grin as she hugged Izuku. 

“Oi! When did that happen?!” Katsuki yelled, his face quickly turning red. 

“I was joking!” Mahoro giggled before darting away. Katsuki growled, chasing after her, but his blush gave him away. 

The door slid open just as Katsuki caught Mahoro. The therapist who often dropped off her baby stepped inside, smiling warmly at Katsuki. 

“You’ve been doing so well, Katsuki. Your therapy seems to be helping. I’ve noticed such a big improvement,” she said. 

Katsuki shrugged nonchalantly, muttering, “Whatever,” but her words lingered. He took baby Riku from her arms, his motions uncharacteristically gentle. 

As Katsuki placed Riku in his crib, Izuku leaned in to kiss the baby’s chubby cheek. Riku babbled happily, as though saying, welcome back. 

Katsuki stood to the side, arms crossed, watching Izuku play with the babies. They climbed all over him, giggling and tugging at his hair as he laughed, his freckled face glowing with joy. Katsuki felt something warm swell in his chest. 

"I wouldn’t be where I am now without them:, Katsuki thought, his eyes softening. "Without him". 

Izuku seemed equally attached to the babies, hugging them and planting kisses on their cheeks. They clung to him more than usual, and Katsuki wondered if it was because of his omega pheromones. But Izuku was wearing a scent patch—maybe they just missed him that much. 

Katsuki didn’t realize he was staring until Izuku turned and held his arms open. “Kacchan! Join us!” he called. 

“Tch. Whatever.” Katsuki rolled his eyes but stepped into the group hug, feeling the soft warmth of the babies squished between him and Izuku. For a moment, everything felt peaceful. 

“Kaa...kaa...” Baby Riku babbled from the crib, grabbing their attention. Katsuki chuckled and picked him up, holding him close to Izuku. 

“Aww, baby, did you miss me?” Izuku cooed, peppering the baby’s cheeks with kisses. Riku giggled, reaching up to pat Izuku’s freckled face with tiny hands. 

When Izuku handed him back, Riku turned to Katsuki and began slapping his cheeks. “Yeah, yeah, slap me all you want,” Katsuki muttered, though he couldn’t hide his grin. 

“Kaa...kaa,” the baby babbled again. 

“He’s trying to say your name!” Izuku gasped. 

“Really? Say Kaa...” Katsuki encouraged, his tone unusually soft. 

“Kaa...kaa...” 

“Now say chan! Say Kacchan!” Katsuki urged, his eyes lighting up. Izuku was surprised at Katsuki referring to himself as Kacchan. "Say Kacchan!" Katsuki repeated. 

“Kaa...kaa...” 

Riku couldn’t quite manage it, but Katsuki looked proud anyway. He chomped the baby’s cheek, earning more giggles. 

As the day went on, Katsuki noticed Izuku zoning out, his usual spark dimmed. He was hiding something behind his smile. There was something really bothering him. 

During nap time, the babies fell asleep quickly, comforted by Izuku’s presence. He lay beside Eri, softly singing a lullaby, while Katsuki sat nearby, keeping watch. 

When the last baby dozed off, Izuku sat up and smiled at Katsuki. “Thanks for looking after them while I was gone. It must’ve been tough.” 

“Tch. These brats annoyed the hell out of me at nap time,” Katsuki muttered, though a faint smile tugged at his lips. 

Izuku chuckled but soon fell quiet, lost in thought. Katsuki eyed Izuku from the corner of his eye. He was looking as if in deep thought. "Oii...  I wanna talk about......some things." Izuku looked at him and nodded. 

They moved to one corner of the room so that their voices could not wake the sleeping pups. They sat on cushions back resting on the wall. After a few minutes of Katsuki remaining sielent Izuku asked, "What do you want to talk about Kacchan?" 

Katsuki seemed out of words so he asked without thinking, " How was your heat?" Izuku blushed and Katsuki regretted asking. 

Shit! What was he expecting to hear? "I was so horny and desperate for a knot Kacchan............" Shit. Shit. Shut. "How was your heat?" What a stupid question, what was he even thinking? 

"It was fine I guess.....I..um...I don't remember much...." Izuku stammered. "I was very scared at first but Kacchan helped me. Thank you. " Katsuki changed the topic sensing Izuku's unease. 

"You look sad  something is bothering you. What is it?" Izuku looked at Katsuki and was going to say," Nothing! Everything is OK but then Katsuki said again, "no need to hide it spit it out." Izuku hesitated, then finally murmured, “I don’t think I can compete with you anymore, Kacchan.” 

“What?” Katsuki yelped, but Izuku quickly shused him, glancing at the sleeping babies. Baby Kota turned in his sleep. Eri opened her eyes for a few seconds then went to sleep again. 

"I presented as an omega Kacchan....... I don't think...you know.... with my secondary gender I don't think I will be able to become a special crime officer....... I don't know if they will accept me at UA Highschool....." Izuku mumbled trying to keep his voice as low as possible. 

"Nonsense! " Katsuki rolledhis eyes. "Why won't they accept you at UA. They are known to be the most inclusive. And who says omegas can't be special officer?" 

Izuku shook his head at that. "But Kacchan...... just think about it. Suppose I am on a mission, I am after a murder or a ....a rapist...and I get in heat.....I will be vulnerable and.......its not safe for omegas.....may be I will do something more simple like being a teacher....I love children after all........" Izuku went sielent. 

Katsuki understood. Izuku’s past trauma that he had hidden somewhere deep was resurfacing again. He kept watching as Izuku was trembling a little. His body acted on its own and he hugged Izuku. Izuku was surprised at first then let go and slumped. 

"Hey! It's OK...I understand. But Izuku... being an officer was your dream. Even before hhe pups were attacked even before you joined the babysitting club.. when we were little brats. I remember even then you wanted to save people. Remember? Remember we wanted to become cops together. I don't know if you remember because we were so small back then. But I remember clearly Izuku. Saving people has always been your dream. Becoming a duo, becoming partners and solving cases, saving people beating the shit out of criminals has always been our common dream. I would save to win and you would win to save. Remember what Inspector Yagi told us?" 

Katsuki felt Izuku hugging him even tighter.  He felt Izuku was sobbing.  "But Kacchan.... I... what if I......" Izuku couldn't complete his sentences. 

"Don't give up on our dreams just because you are an omega now. You being an omega changes nothing. I am an alpha remember. Like omegas alpha also go into rut. It's the same for both alphas and omegas. People don't like to mention it but alphas in rut are equally vulnerable as omega in heat. Ruts are annoying too. But look I am not going to let ruts pull me back and prevent me from achieving my goals. There are scent patches, natural supplements and even suppressants available. We will make it work. OK?" Izuku shook his head. 

"And about being a teacher, you can always teach if that is something you want to do. Part-time teacher and part time special cop. Sounds badass to me." Izuku looked at Katsuki who was smiling. Izuku smiled too then hid his face in the embrace one again. 

"I am not pressuring you. People change. Their goals change. Its OK. But I want to let you know that whatever path you choose Izuku. I am with you." 

Katsuki closed his eyes as Izuku stayed still in his arms. It was as if time had frozen. Katsuki ruffled Izuku's curls. And Izuku hummed. 

"Let's become partners Kacchan. " Izuku looked up at Katsuki. They both smiled. That was when Katsuki noticed. They were so close. Their faces were just inches apart when a groggy voice interrupted, “Are you two going to kiss?” 

Mahoro stood, rubbing her eyes. Izuku jumped up, his face red. “You’re awake? Let’s get you back to sleep,” he said, quickly scooping her up. 

Katsuki stayed frozen, his mind racing. When Mahoro was asleep again, they avoided each other’s gaze. Katsuki muttered something about dishes and escaped to the kitchen, while Izuku curled up beside the sleeping kids. 

By the time Izuku woke, Katsuki was dozing, cuddled between Katsuma and Mahoro. Baby Riku was awake in his crib, pointing at a crow outside. 

“Kaa...kaa...” Riku babbled. "Caw....Caw...." "Kaaa....kaa..." The baby repeated after the crow. 

Izuku smiled softly. “Poor Kacchan,” he whispered. Katsuki had been so excited earlier, thinking the baby was calling his name but seems like he was just mimicking a crow. 

But as Izuku looked at Katsuki’s sleeping face, peaceful and unguarded, he felt a sense of calm. Whatever happens, we’ll keep competeing Kacchan. For the rest of our lives..........

"Good afternoon," Shoto said, bowing politely in front of Aizawa. 

"Good afternoon," Aizawa replied, with Izuku chiming in, his voice cheerful. 

The pups peeked out nervously from behind Katsuki, who stood protectively in front of them. Katsuki glared at the new visitor, his instincts on high alert—a new Alpha had entered his territory, and he didn’t like it. 

"You must be Todoroki, if I’m right," Aizawa said. 

"Yes, sir," Shoto replied with a small bow. 

"Inspector Enji called me earlier, informing me about your visit." 

Shoto nodded. "I came here to apologize on behalf of our family. We’re very sorry about what Toya-ni did." He bowed deeply again. 

"Toya-ni?" Izuku asked, tilting his head, his green eyes filled with curiosity and confusion. 

Shoto looked at Izuku and nodded. The two of them locked eyes, a quiet moment of mutual observation. 

Katsuki’s growl broke the silence as he stepped in, pulling Izuku close to his side, glaring at Shoto with open hostility. "Kacchan?" Izuku murmured, gently rubbing Katsuki’s arm in an attempt to calm him. 

"He’s Dabi’s brother," Katsuki scoffed. 

"Dabi?" Izuku’s voice rose with concern, his protective instincts flaring as he looked at Shoto, then back at Katsuki. "The one who tried to kidnap you and the pups?" 

The mention of Dabi made the pups scatter and run inside, their small forms disappearing quickly. Izuku’s expression shifted into something fierce, his eyes narrowing suspiciously at Shoto. 

"Yes," Shoto said, his voice tinged with guilt. "I’m very sorry for what Ni-chan did. He’s in jail now. I wanted to come here to personally apologize—" 

Aizawa interrupted, speaking calmly to diffuse the situation. "Todoroki is here to help today. Let’s focus on that for now." 

But Katsuki wasn’t ready to let go of his anger. His growling grew louder, his territorial instincts clear. Seeing Izuku’s growing anxiety, Aizawa handed scent patches to both alphas, forcing them to calm down. 

Poor Shoto. The pups were terrified of him, and Katsuki refused to let him get anywhere near the babies. Izuku, tried to bridge the gap. He spoke with friendliness to Shoto, slowly breaking the ice. 

Mahoro, the bravest of the pups, was the first to approach Shoto. "You’re handsome, mister," she said with a shy but sincere smile. 

"Indeed he is," Izuku added with a cheerful laugh, making Eri giggle as she toddled over to Shoto, staring up at him with wide eyes. Katsuki bristled. 

Shoto, though visibly low on social energy, handled the pups with surprising gentleness. He knelt down to their level, letting them approach at their own pace. Soon, all the pups except Kota and Riku gathered around him. The two holdouts stayed with Katsuki, their cheeks puffed out in synchronized irritation. The three watched Shoto's every action and longed for Izuku’s attention on them. 

As the girls declared Shoto the "handsome prince" in their princess game, they roped Izuku into being their "fairy godmother." Poor Katsuma got the role of the princess's pet puppy. The play went on for sometime. Until it became too annoying. 

Katsuki, still sulking, suddenly stood up. Placing baby Riku in his crib, Katsuki dramatically declared himself the "Dragon King." With a loud proclamation, he scooped up Izuku like a sack of potatoes. "Dragon Kota, let’s go!" he shouted, recruiting the boy into his antics. 

What followed was utter chaos. Katsuki and Kota "attacked" the handsome prince while Eri and Mahoro protested loudly. "You ruined our princess game!" they yelled. Even the loyal pet Katsuma joined Katsuki’s little army. Meanwhile, baby Riku clapped and giggled, loving the spectacle. 

Izuku, slung over Katsuki’s shoulder, laughed so hard he could barely breathe. Shoto, watching the chaos, let out a rare, soft smile. 

When it was time for Shoto to leave, Eri and Mahoro hugged him tightly. "Will you come back, Prince?" Mahoro asked with a bright smile. 

"Yes, I will come back for you, Princesses," Shoto promised, his voice warm and sincere. 

"No need," Katsuki muttered under his breath. "Just stay away, you brother of a kidnapper." 

Izuku rolled his eyes, laughing as he gave Katsuki a reassuring hug. "Don’t mind him Todoroki. Kacchan’s just jealous you stole his little princesses. He’s acting like a protective girl dad." Katsuki hugged Izuku back tightly, smirking as he shot Shoto a middle finger. 

Shoto blinked, unfazed but slightly confused. "Good thing the kids didn’t see that," he thought, shaking his head as he turned to leave. 

As Shoto walked out of the babysitting club with Mahoro, Katsuma, and their dad, Mahoro tugged at his pants. He crouched down to listen to her. 

"I think Katsu-ni-chan likes Izu-ni-chan," she whispered with a giggle. 

Shoto nodded in agreement, his face calm, but the corners of his lips lifted ever so slightly as Mahoro skipped away.

* 

Izuku gently patted baby Eri’s soft hair, his hand moving carefully to avoid waking her. He was lying sideways on the futon, pressed against Kacchan’s chest. Katsuki’s warm breath brushed against the back of Izuku’s neck as he lazily played with Izuku’s curls, twisting them between his fingers. His face was so close to Izuku’s scent gland that the earthy, minty aroma was probably calming him down. Izuku had stopped wearing his scent patch whenever possible, knowing how much it soothed Katsuki. 

Katsuki must’ve picked up on the faint shift in Izuku’s scent. “Oi. What’s bothering you?” he whispered near Izuku’s ear, his voice low and gruff. “Does it still hurt?” he asked, cupping Izuku’s bottom where he had kicked him earlier during their special 'Future Cops Training'. 

Izuku let out a soft squeak. “N-No, it’s fine!” He flushed pink, and Katsuki quickly pulled his hand away, trying not to think about how soft and squishy Izuku's ass had felt under his palm. 

“Then what is it, nerd? You smell… I don’t know, kinda sad,” Katsuki muttered. 

Izuku turned to face him, eyes already glistening with tears. “We only have a week left, Kacchan,” he whispered, his voice trembling. Katsuki’s gaze flickered between Izuku’s tearful expression and the sleeping pups beside them. Mahoro and Katsuma were snuggled together, Eri was sucking her thumb, Kota was kicking in his sleep, and little Riku clung tightly to his plushie. 

“We won’t get to see our babies anymore…” Izuku’s voice cracked, and Katsuki could tell his omega instincts were hurting. 

“Quit whining. It’s not like we’re dying or anything. We can drop by any time we want to check on these brats,” Katsuki said, brushing it off like it wasn’t a big deal. 

Izuku pouted, his lips trembling. “You’re happy, aren’t you? Happy you won’t have to change diapers or play princess-princess with them anymore.” 

Katsuki rolled his eyes. “Kind of,” he admitted with a huff, though the corner of his mouth twitched. Izuku looked offended, but before he could start scolding him, Katsuki let out a soft chuckle. 

“Listen, nerd. I’ll miss them too. A lot, actually.” He glanced back at the pups. These little brats had been a handful, sure, but they had brought out a side of himself he didn’t even know he had—a protective, caring side. And Izuku… being with these kids had helped him, too. They’d helped Izuku heal from his past trauma and brought out his nurturing omega side in a way that Katsuki had grown to love. 

“We can come back on weekends,” Katsuki said, brushing a stray curl from Izuku’s face. “Maybe continue those self-defense lessons. The pups would love that.” 

Izuku hummed softly but looked away. “Do you think they’ll miss us after we leave?” 

Katsuki gave a small, knowing smile. “They’ll miss you for sure, nerd. Maybe me too. Especially kicking me and yanking my hair.” 

Izuku giggled softly at that. “Aizawa sensei said there’ll be a new caretaker soon. Students won’t be able to volunteer anymore so he will have to add a staff.” His smile faltered a little. “What if they don’t take care of the kids the way we do?” 

Katsuki chuckled. “Are you jealous, nerd? Worried someone else might get close to our babies?” 

Izuku gave a small nod. Katsuki patted his head “They won’t be here forever. Most of them will be starting kindergarten soon. And Riku’s mom said she might take a break from work to be with him more. She’s jealous his first word might be ‘Kacchan,’ not ‘Mama.’” 

Izuku smiled at that, Katsuki still firmly believed Riku was trying to calling him “Kacchan”. 

“Yeah, there’ll be new babies here eventually." Izuku agreed. "It’s just like us, Izuku,” Katsuki said, his voice softening. “We’ll leave middle school and move on to high school. Everyone goes their separate ways. We can’t keep people glued to us forever.” 

“But, Kacchan…” Izuku’s voice wavered again. “I’m not sad about leaving middle school. It’s just… I don’t have any friends.” His green eyes looked up at Katsuki, shimmering with hurt. 

Katsuki’s face darkened for a moment before he sighed. “Yeah… me neither.” He hesitated, then let a soft smile creep onto his face. “But I do have one friend. And that one friend is going to UA with me, so I guess I don’t feel so sad after all.” 

Izuku’s tears turned into laughter, and Katsuki joined in. The quiet sound of their laughter filled the room, blending with the soft snores of the sleeping children around them. 

Izuku hugged Katsuki. And Katsuki wasted no time burying his face in the crook of Izuku’s neck. The 'Happy Izuku' scent hit him hard. He could feel Izuku’s breath on his neck. Guess Izuku was also doing the same. Katsuki peeled his own scent patch off and the air filled with scent of burnt caramel and spices. 

Izuku felt his omega rumble and a purr escaped his lips. Katsuki's alpha answerd with a low growl. Suddenly Katsuki understood that their innocent-platonic hug was turning into something not-so-innocent. 

*

Huff....

Huff...

"Kacchan! Go deeper!" 

"I am trying!" Katsuki stilled for a second trying to catch a breath. 

"Faster Kacchan." 

Katsuki chuckled. "Huff...Huff.....So impatient."

He increased his pace. He kept hitting the same spot. 

"Yes there Kacchan."

Katsuki kept going. 

"I’m getting bored!" Kota groaned, flopping onto the ground dramatically. 

"Just a little bit more," Izuku said, ruffling his hair fondly. 

"Aw...wuwu...auwuwu!" Baby Riku babbled excitedly, tied snugly to Izuku’s back in a carrier, his tiny fists waving in the air as if cheering for Katsuki. 

Katsuki chuckled, wiping the sweat from his forehead. "Yeah, yeah! Just a little more digging. This place is full of rocks, so it’s taking longer." He slammed the hoe into the ground again, grunting as he unearthed a particularly large stone. 

"You’re so strong!" Mahoro cheered, clapping her hands. 

Katsuki grinned and flexed his biceps for her, playing along. "Damn right, I am!" 

"Stop showing off and dig faster!" Kota snapped, crossing his arms. 

Katsuki shot him a sharp glare, and Kota yelped, quickly darting behind Izuku for protection. 

"Is this jar okay?" Katsuma and Eri called out, running up with a glass jar held carefully between them. 

"It’s perfect!" Izuku beamed, crouching down to take it. Together, they began filling it with small papers and mementos: 

• Mahoro and Katsuma’s crayon drawing of Katsuki looking like an angry devil. 

• Kota’s sketch of Izuku heroically saving him from Muscular. 

• Eri’s heartfelt letter addressed to Izuku (she didn't know how to write so Katsuki wrote it for her). 

• A paper with Baby Riku’s tiny hand and footprints, smudged but precious. 

"Is it deep enough?" Katsuki asked, tossing the hoe aside and brushing dirt off his hands. 

"Yes, it’s perfect," Izuku replied, kneeling beside the pit Katsuki had dug. 

Carefully, they lowered the little glass time capsule into the hole, the kids leaning in eagerly to watch. 

"It’s done," Izuku said softly, patting the dirt back into place as the children crowded around him. 

Katsuki stood back, wiping his hands on his pants as he looked at the freshly covered pit. "A time capsule, huh?" 

"A time capsule full of memories," Izuku said, smiling up at him. "Of a summer we spent together in The Babysitting Club."

Chapter Text

It was their final day in the Babysitting Club. Katsuki noticed how Izuku looked sad. He held Izuku’s hand, and Izuku looked up at him. Katsuki gave a reassuring smile, and Izuku returned it with his own. 

They walked inside the childcare and were surprised to see all the pups already gathered, shouting, "Welcome!" and throwing confetti. Baby Riku babbled and clapped from where Aizawa was holding him. 

"Aww... thank you so much," Izuku said, kneeling down to give his babies a group hug. Soon, Mahoro held out her hand to Katsuki, signaling him to join. "Tch..." Katsuki clicked his tongue but still took her hand and joined the group hug. 

After the hugging was over, Aizawa made them clean up the confetti. Katsuki scowled while Izuku laughed at his reaction. 

It was time for their daily physical training and self-defense class. As usual, Izuku started the warm-up, making the pups dance to a nursery rhyme. "One little duckling cluck..cluck...cluck...." The babies waddle and danced just like little ducklings. Then Katsuki stepped in, teaching them techniques for what to do during disasters. 

The whole day, they played with the babies. It felt like any other day, but the pups were clingier and more obedient. Izuku was also unusually clingy, hugging and kissing the babies every two minutes. Katsuki was trying his best not to be rude or shout. 

When it was nap time, all the pups cuddled with both of them. Everyone fell asleep, but then Katsuma mumbled in a sleepy tone, "Izu-ni-chan, Katsu-ni-chan! Please don't leave." He then fell asleep on Katsuki's chest. 

Izuku looked surprised and started sniffling. "Hey, hey! Don’t cry," Katsuki said, but Izuku started sobbing. 

"Shh... the pups will wake up," Katsuki whispered, pulling Izuku close and wiping his tears. 

"Nerd," Katsuki chuckled. "Don’t worry! They’ll be alright without us. We’ll come to see them time and again." 

Izuku nodded and looked around. The kids looked so peaceful while sleeping. He glanced at Katsuki, who was smiling fondly at Katsuma on his chest while gently playing with Mahoro's pigtails. Izuku could sense the protective and happy alpha scent, and it lulled him to sleep. 

When it was time to go home, the pups and Izuku tried hard to hold back their tears. Aizawa gave a small speech, thanking his problem children. Izuku followed with a heartfelt speech about how much he enjoyed being there and how much he would miss everyone. 

The babies and Izuku were on the verge of tears when Katsuki started his speech. "I’m happy I won’t need to change diapers or play princess ever again. And no more brats pulling my pants down!" 

The kids burst into laughter, completely distracted, and started jumping and hitting Katsuki. Katsuki laughed along with them, and even Izuku joined in. Aizawa smiled softly as the kids all hugged Katsuki. 

"I will also miss you brats!" Katsuki said. 

"Kaa... kaa... chaan... kaa-chan," Baby Riku babbled, crawling toward Katsuki. 

Everyone gasped. 

"Say that again!" Katsuki exclaimed, scooping the baby into his arms. 

"Kaa-chan! Kaa-chan!" the baby repeated, slapping Katsuki's cheek with his tiny hand. 

"Oh my god! So he was really trying to say your name!" Izuku said, stepping closer. He saw Katsuki smiling so beautifully, his eyes shimmering like silver. It was so rare to see him emotional like this. 

"Huu... bah... bah," the baby babbled, clapping his little hands. Katsuki chuckled, kissing the baby and playfully chomping his cheek. 

"Thank you, pups. Thank you, Izuku. Thank you, everyone, for making me who I am now," Katsuki thought as parents began arriving to pick up their kids. 

When the childcare center finally closed for the day, Katsuki and Izuku walked home under a sky painted golden by the setting sun. Katsuki glanced at Izuku’s smiling face, then at their joined hands, and whispered to himself, "Thank you. I will miss you, MY BABYSITTING CLUB."

Chapter Text

"Umm, Kacchan!" Izuku purred, hugging Katsuki. Katsuki’s alpha rumbled.

“You’re back,” Izuku chirped. Katsuki smiled, and they walked hand in hand, waving goodbye to Inko. 

It had become a ritual for them—Katsuki would come to pick Izuku up for school every morning, and Izuku would drop Katsuki home after school. Some days, Katsuki would arrive a little earlier to help Inko cook or get Izuku ready. Other times, Izuku would stay over at Katsuki's after dropping him off to do assignments together. 

Today, when Katsuki arrived, Izuku immediately jumped into his arms, hugging him tightly. Katsuki had missed school because of his rut. And they both missed each other. 

Katsuki smiled at their joined hands. Izuku looked like a puppy with that bright, innocent grin. Katsuki tried not to think about the wild fantasies that had consumed him during his rut. He looked away, feeling the aftereffects still stirring inside him. 

The day at U.A. started like any other. Once they entered the school, Izuku’s friends pulled him away, and Katsuki was surrounded by his usual group of idiots. Kirishima side-hugged him, Mina ruffled his hair, Sero smirked like the clown he was, and Kaminari made a crude comment about ruts and fantasies, clearly proud of himself. 

Normally, that would have earned Kaminari a smack from Katsuki, but Katsuki was distracted. His gaze had drifted to Izuku, who was standing with Iida, the boy’s hand resting on Izuku’s shoulder in a half-hug. Izuku was smiling, listening to whatever the four-eyes was saying. Tsu high-fived him. Then Uraraka got too close, her hand brushing Izuku’s arm, and Izuku smiled at her, too—blushing slightly. 

Why was he blushing? 

Katsuki’s jaw tightened as he watched Izuku dab his hand with Uraraka’s, and then that half-and-half bastard approached. Shoto casually stood beside Izuku, and the two began talking. Katsuki’s hands clenched into fists. What the hell were they talking about? 

Izuku glanced at him for a brief second, smiling, and Katsuki instinctively smiled back.

Maybe he was overthinking things. 

Then Izuku held Shoto’s hand, and the Dekusquad walked toward the classroom together. Katsuki silently followed, leaving his confused friends behind. 

“Did you see that?” Mina asked, breaking the silence.

“Bakugo didn’t even beat me after my comment,” Kaminari said, sounding incredulous.

“No, not that, idiot,” Mina said, rolling her eyes. “Did you notice how he was gawking at Midoriya?” 

Kaminari and Sero exchanged shocked looks, while Kirishima just chuckled.

“What about that? He was just looking at his childhood friend,” Sero said. 

Mina laughed. “Yeah, childhood friend.” 

Kirishima shook his head with a knowing smile. “Haven’t you two noticed? Bakubro is always looking at Midoriya.” 

“Hey, don’t tell me you haven’t noticed either!” Mina said, grinning. “I think they’re together.” 

Sero gasped loudly. “Really?”

“Shh!” Mina hushed him. “Yeah, I’ve always noticed it. Bakugo always sits in front of Midoriya. Midoriya draws little things on his back with his fingers, and Bakugo never gets annoyed. He actually looks... happy. And whenever Shoto gets too close to Midoriya, Bakugo goes into full pissed-off mode. 

“Also, during physical training, whenever Midoriya does well, Bakugo has this proud smile. And have you noticed that it’s always Bakugo who pulls out Midoriya’s lunch? He literally brings lunch for him!” 

“Yeah!” Kaminari chimed in. “I never thought Bakugo was into anyone—girls or boys—but I see it now. And Midoriya is so clingy to his Kacchan! Like, ‘Sugoi Kacchan! Kacchan is amazing! You’re the best, Kacchan!’” Kaminari mimicked Izuku in a high-pitched voice. 

They all laughed, except Kirishima, who had a faint smile and seemed lost in thought. 

“Oii, what’s on your mind?” Mina poked his cheek. 

“Mina, remember when we were in middle school? I once told you about a boy saving his friend from being kidnapped...” Kirishima trailed off. 

Mina thought for a moment before nodding. “I remember vaguely... What does that have to do with anything?” 

“That was them. Midoriya saved Bakugo from being kidnapped. And did you know Bakugo almost got arrested for beating up some high school guys who were messing with Midoriya?” 

“Seriously?” they all said in unison. 

“How do you know all this?” Mina elbowed him. 

“It was on the news—well, a local channel. They aired it briefly before the police asked them to stop, to protect the boys’ reputations. And...” Kirishima hesitated. “Bakugo once told me they weren’t close back then. In fact, he used to bully Midoriya.” 

“What?” Mina exclaimed.

“No way! He’s so protective of Midoriya now,” Sero said, looking skeptical. 

“Well, it’s Bakugo we’re talking about,” Mina said thoughtfully. “Apparently he’s changed.” 

Their chatter continued until the bell rang, and they scrambled into the classroom, laughing like the bunch of idiots they were.

.....

“What? Are you sure?” Katsuki looked at Izuku for a second, disbelief evident in his expression. “No, there should have been a mistake,” he said louder. 

Izuku watched him with concern. It was during lunch when Katsuki received a call from the elementary school teacher. 

“Shit!” Katsuki facepalmed after the call ended. 

“What happened, Kacchan?” Izuku asked, tugging at Katsuki’s arm. 

Katsuki plopped back into the seat where he had been sitting with Izuku earlier, letting out a long sigh as he rested his head on Izuku’s shoulder. “Our pups created trouble at school,” he mumbled. 

“Oh no! What did they do this time?” Izuku gasped, waiting for an answer. Katsuki stayed silent. 

“Kacchan, what did our babies do?” Izuku shook him lightly, his voice rising with urgency. 

“Kota beat up a guy in his class,” Katsuki muttered, covering his face with his hands. “And Mahoro joined him.” 

Izuku gasped again. “My babies! Why did they—? It’s because they take after you, Kacchan!” he huffed, puffing out his cheeks in frustration. 

“Oi! What did you say?” Katsuki lifted his head, glaring at Izuku. 

“It’s because they take after you,” Izuku repeated, crossing his arms. “They got their temper from you. That and the fighting. You taught them self-defense, but look how they’re misusing the techniques we taught them!” 

Katsuki leaned over to pull Izuku’s cheeks with a mischievous grin. “Nah! It’s all because you pamper them so much. You’ve spoiled the brats rotten. Now they don’t even listen to me. How many times have I told you—you shouldn’t spoil your pups so much!” 

“My pups?” Izuku’s tone shifted, his face now a mix of anger and sadness. A furious omega scent radiated faintly from his exposed neck. “My pups? They’re your pups too! When they do something good, you always say, ‘My pups, my pups are awesome like me, they take after me.’ But when they do something bad, they’re suddenly your pups?!” Izuku’s voice shook as he puffed out his chest. “Don’t spoil your pups so much? Don’t—” 

Izuku trailed off, mumbling under his breath, while Katsuki watched him with an amused grin. 

“Okay, okay! Sorry!” Katsuki said with a laugh. 

Izuku looked up at him, his expression softening slightly. Even after so much time, he wasn’t used to hearing words like “sorry” from Katsuki. 

“They’re my pups too. And okay, they take after me,” Katsuki admitted, ruffling Izuku’s hair with a smirk. 

Izuku pouted for a moment before his lips quirked into a small smile. They sat like that, the tension easing, until Katsuki leaned in closer and buried his face in the crook of Izuku’s neck. He inhaled deeply, taking in Izuku’s calming scent, and let out a low groan. 

“The teacher wants to have a meeting with us,” Katsuki murmured into Izuku’s neck. “Today.” 

Izuku patted his back gently, his own shoulders slumping. “Oh no! We’re in trouble too. What are we going to do, Kacchan?” 

Katsuki pulled back just enough to meet Izuku’s gaze. “I don’t know,” he admitted, a rare look of helplessness crossing his face. 

............ 

Kaminari and Sero sprinted down the hallway, bursting through the door with such force it rattled in its frame. 

“Guys! We have news!” Kaminari exclaimed, out of breath. 

Everyone turned to look at them. The room wasn’t too crowded—Uraraka, Iida, Kirishima, and Mina sat scattered, chatting casually. 

“Wow, wow, wow... Stop! Breathe!” Mina patted Kaminari and Sero on the back, guiding them to sit down. 

“You’re not going to believe this,” Sero began, his face still flushed from running. 

“Yeah, but lower your voice, Sero!” Kaminari whispered dramatically. “We don’t want this scandal to spread like wildfire.” 

Mina leaned closer, intrigued. “What is it?” 

Kaminari gestured for Uraraka and Iida to come closer. “Guys, you need to hear this. Come here.” 

Iida frowned. “Sorry, it’s not good to gossip about—” 

Kaminari interrupted him. “But it’s about Midoriya. It’s really serious. Just come here!” 

Reluctantly, Iida joined them, and the six of them formed a tight circle. 

“So,” Sero began, “we actually thought about what Mina said this morning and decided to keep an eye on Bakugo and Midoriya. We followed them when they went to have lunch, and…” 

“We took this device that helps you hear from far away,” Kaminari added. 

Iida’s face darkened. “Wait, are you saying you stole Jirou’s headphone device to spy on—” 

Mina cut him off, waving a hand. “Let them finish!” 

Sero continued, “So, we saw them head to their secret spot, and as soon as they got there, Bakugo and Midoriya took their scent patches off… and hugged. They took each other’s scent straight from the source…” 

Uraraka gasped. “Why would Bakugo do that?” 

Mina blushed, while Iida looked deeply uncomfortable. Kirishima, on the other hand, smirked like a dog with a bone. 

“And then?” Mina pressed excitedly. 

“Then they ate lunch,” Sero said. “Bakugo fed Midoriya, and Midoriya fed Bakugo. Midoriya even said—” 

“Oh! Kacchan’s cooking is amazing! I missed this so much,” Kaminari mimicked in a cringy, high-pitched voice. 

Sero picked up the story. “And then Bakugo laughed and said…” 

“‘Okay, nerd, I’ll cook you katsudon for dinner tonight,’” Kaminari chimed in again. 

Mina clapped her hands together. “Wow, that sounds so… so domestic.” 

Uraraka’s pink cheeks turned even rosier. Iida looked as though he wished the ground would swallow him, but he didn’t move to leave. 

“What happened next shocked us both,” Kaminari said, his tone suddenly serious. 

“Hey, don’t keep us in suspense! Say it!” Kirishima urged. 

“Oh my god, oh my god! Did they… did they kiss?” Mina asked, covering her face dramatically. 

“No… they made babies!” Sero exclaimed, dropping the bombshell. 

“What?!” The group screamed in unison, their faces horror-stricken. 

Kaminari started babbling, “Yeah, they’re parents! They have their own pups, and their pups beat some guy up at elementary school today. The teacher called to complain, and then Midoriya said it was because the dad of the babies was always angry and fighting, so the pups turned out like that. Then Bakugo said it was because Midoriya spoiled them too much. They argued, and Midoriya got angry, and then Bakugo said sorry, and then—” 

“Wait, stop, stop! What are you even saying? Babies?” Uraraka’s voice trembled with disbelief. 

“They’re not even 18 yet—they’re too young!” Iida yelled, his composure crumbling. 

“Bakubro hid such a big thing from me? I thought I was his best friend…” Kirishima said sadly. 

“So you’re telling me they have pups? Are you serious?” Mina screamed. Chaos erupted among the group. 

“Okay, let’s stay silent for a moment,” Iida commanded, his voice unusually strained. “Tell us the truth. Please tell me this isn’t some kind of sick joke.” 

“It’s not a joke,” Kaminari said. “We’re serious. We heard everything. Even without the device, we could see and hear them clearly.” 

Sero summarized briefly, “There was a call for Bakugo. After it ended, he told Midoriya their babies got into a fight and that the teacher wanted to meet with them. Midoriya and Bakugo had a little fight—well, more like flirting than fighting—and now they’re going to the meeting.” 

Everyone gasped, exchanging wide-eyed looks. 

“They’re in high school and have pups who go to elementary school,” Uraraka said, her voice filled with disbelief. “They… did it? Midoriya looks too innocent for all this.” She blushed, covering her face. 

“I think it was accidental,” Kirishima said thoughtfully. “They were both newly presented and have so much history together…” 

“That might be true,” Mina agreed. “Maybe during their first heat or rut… who can fight against instincts…” 

“Dude, that means Bakugo’s sperm must be super potent. Getting a male omega pregnant isn’t easy. He knocked up poor Midoriya the first time!” Kaminari’s comment earned him a sharp bonk on the head from Mina, while Iida and Uraraka looked like their souls had left their bodies. 

“We shouldn’t judge them,” Iida said after a pause. “Yes, it’s scandalous and… inappropriate for their age, but we should respect their decision to keep the pups. Maybe they didn’t tell anyone because they feared we would judge them.” 

The group fell silent at Iida’s words. 

“It must have been really tough for them,” Kirishima said. “They were so young and had to take on such a big responsibility. It must have been difficult for Midoriya, and Bakugo probably drowned himself in guilt.” 

“Yeah. Bakubro is someone who keeps blaming himself,” Kirishima continued. “Even if he doesn’t show it, he feels guilty about Midoriya. I’ve seen the way he looks at him sometimes…” 

“And they were in middle school,” Uraraka said softly. “How did they even manage everything?” 

“Not to mention Bakugo topped the entrance exam, with Midoriya close behind him. They’re always competing—whether it’s in studies or sports. They did so well in the sports festival.......umm....except for how Bakugo acted like a wild beast after winning.” Mina added. 

“And they’ve recently started interning for Ex-Police Officer Yagi Toshinori. They’re working at a private investigation agency,” Uraraka added. 

“They’re amazing!” Kaminari said. 

“Yeah. It’s good that they’re happy and shaping their careers,” Iida agreed. 

“Oh… I can’t stop thinking about what the babies look like,” Mina said, her eyes lighting up. 

“They must be scary, like Bakugo,” Kaminari guessed. 

“Or cute, like Midoriya,” Uraraka said, smiling. 

“Isn’t there a way we could see them?” Sero asked. 

“I want to see them so badly. Bakugo and Midoriya’s babies—they must be adorable!” Mina said, pretending to pinch cheeks. 

“They’re very cute,” a monotone voice said suddenly. 

The group jumped and turned, startled. Standing behind them was Shoto, his face as unreadable as ever.

..............

“Todoroki, when did you…?” Iida trailed off. 

“I just got here. Were you talking about the pups?” Shoto’s question made everyone tremble. They scrambled to think of something to tell him, but Shoto sighed before they could respond. 

“I miss them. Bakugo won’t let me see them.” 

They all froze, confusion written on their faces. 

“Wait! You know about the babies?” Kirishima exclaimed. “Bakugo told you but didn’t tell me?” He pouted, and Mina patted him sympathetically. 

“How do they look?” Mina asked excitedly. 

“Squishy…” 

“Huh?” Everyone blinked at Shoto’s unexpected answer. 

“Their cheeks are very squishy,” Shoto clarified, making a gesture with his hands as if squishing imaginary cheeks. “They were so small. They grew up so fast.” 

“You’ve known them since they were small?” Kaminari asked. 

“Yes. I used to babysit them sometimes. Actually…” Shoto hesitated. “My Ni-chan once tried to kidnap Bakugo… and he tried to kidnap the babies too.” 

A stunned silence fell over the group. 

“That was in middle school. I used to visit the childcare center to see them sometimes. Then they started going to kindergarten, and I’d visit them there too. But ever since the Sports Festival, Bakugo hasn’t let me near Midoriya or the babies.” 

“Was it because of what happened to Midoriya?” Sero asked cautiously. 

“Yeah. I accidentally hurt him, and then he couldn’t play. He ended up in fourth place. Bakugo wanted to face him in the finals, not me. That’s why he acted the way he did that day. Even though he won, he was sad for Midoriya.” Shoto’s face dropped, his calm expression clouded by regret. 

“Do you know which school the pups go to?” Kaminari asked, his voice filled with curiosity. “We could go there and see them.” 

"No. They started school last month. But I don't know which school." Shoto said running his fingers through his hair. 

Mina’s eyes lit up with excitement. “Guys, I have an idea! Bakubabe won’t let us near his pups—he’s such an overprotective alpha. But Midoriya is a total sweetheart. Let’s just ask him directly!” 

Shoto nodded. “If we persuade him, he won’t be able to say no.” 

The group waited for the perfect moment to find Izuku alone, which was almost impossible. But Mina, quick to act, dragged Izuku away, claiming it was an omega-related matter. Katsuki tried to stop her, but Kirishima intervened, pulling him aside with an excuse about learning high-jump techniques. 

When Mina brought Izuku into an empty room, he hadn’t expected to see Shoto, Iida, and Uraraka waiting there too. Seeing the group of alphas and betas made him realize this wasn’t about omega things at all. 

“Guys, what is this all about?” Izuku broke the silence, his voice tinged with nervousness. 

“Well… um… we know your secret… about the babies,” Uraraka said in such a low voice that it was hard to hear. 

Izuku looked a little surprised, his eyes flicking to Shoto, who nodded. 

Iida stepped in. “Please don’t get us wrong. We’re very happy for you and Bakugo. Taking care of the pups must be tough, right?” 

Izuku smiled sheepishly, starting to mumble as he often did when he was nervous. “Yeah, babies… I remember… it was after Kacchan’s first rut… then he got into a  fight because of me…........he apologised....... he was good to me........and then… and then Kacchan also joined… and then I went into heat… then…” 

Those were the only clear words the group could understand through his mumbling. Uraraka, Mina, and Iida were blushing furiously, their faces bright red. 

“It’s okay, Midoriya! You don’t have to explain… it… to us,” Iida said quickly, patting him on the shoulder with a sympathetic smile. 

Izuku, puzzled by their reactions, glanced at the red-faced Mina and Uraraka, then at Shoto, who looked just as confused as he was. 

“Midoriya! Can we see your pups?” Uraraka asked suddenly, her voice filled with hope. 

“Please, please, please, please!” Mina jumped up and down. 

“Let me see the pups. I miss them. If you ask Bakugo, I’m sure he’ll let me see them,” Shoto added, taking Izuku’s hands earnestly. 

Izuku looked to Iida, who smiled and said, “I’d like to meet them too.” 

“Okay,” Izuku finally agreed, though he wasn’t entirely sure how Kacchan would react to this. 

........... 

Katsuki looked ferocious. His jaw was clenched tight, his teeth gritting audibly, and his crimson eyes burned with a murderous intensity. He looked like he was ready to tear into anyone who dared step too close. 

“Kacchan... please calm down,” Izuku said softly, stepping closer to him. He gently rubbed his wrist scent gland against Katsuki’s, trying to soothe the storm brewing inside him. 

Katsuki’s fiery gaze flicked down to Izuku, his expression unchanging at first. But as Izuku smiled up at him, Katsuki rolled his eyes and let out an exaggerated huff. 

The group walking behind them came to a halt. Most of their friends exchanged nervous glances, clearly hesitant to come any closer. Even Ochako and Kirishima, who were usually unfazed by Katsuki’s temper, seemed cautious. Only Iida and Shoto remained calm, their faces expressionless. 

Katsuki growled low in his throat, the sound reverberating like an approaching storm. 

“Kacchan... they’re our friends,” Izuku reminded him, placing a hand on Katsuki’s arm as if anchoring him. 

Katsuki stopped abruptly, his body coiled like a predator ready to pounce. “Why the fuck are they following us?” he snarled, his voice low and dangerous. 

Izuku sighed, stepping in front of him to block his line of sight. “Because they want to see our pups,” he said calmly. 

Katsuki’s head whipped around, his fiery gaze locking onto Shoto. “And who the fuck told these idiots about them?” 

Shoto blinked, his face unreadable. Before he could respond, Izuku quickly intervened. “They found out themselves,” he said, trying to defuse the situation. 

“Fuck off! They’re not going anywhere near—” Katsuki’s words were cut off as he surged forward, as if to attack. 

Izuku moved swiftly, catching him before he could take another step. It was almost like a hug, his arms wrapping around Katsuki in an embrace that was more restraint than affection. 

“Enough, Kacchan! You’re overreacting,” Izuku said firmly, though his tone remained gentle. 

For a moment, it seemed like Katsuki might fight back, his muscles taut and his anger unrelenting. Then, with a sharp “Tch,” he stilled. 

Without a word, Katsuki turned on his heel, grabbing Izuku’s hand and tugging him forward. His pace was brisk, but the explosive energy that had surrounded him just moments ago had dissipated, leaving only a lingering tension. 

The group exchanged relieved glances behind them before cautiously following at a safe distance. 

"No need to feel embarrassed, Bakubro… we don’t judge you," Kirishima said with a wide grin, trying to lighten the tension. 

Katsuki shot him a glare that could have leveled a building. How could he not feel embarrassed? His tough, cool-guy image was shattered now. These losers—his losers—knew that he had been changing diapers and cleaning up after a couple of brats. His brats. 

“Are you really embarrassed about our pups, Kacchan?” Izuku asked, his voice soft and full of concern. He looked up at Katsuki with wide, sad eyes and an unmistakable pout that made Katsuki’s heart twist uncomfortably. 

“No!” Katsuki barked, maybe a bit too loudly. The sharpness of his tone made Izuku flinch slightly, so he exhaled and softened his voice. “No,” he repeated, more earnestly this time. 

And it was true. Yeah, he was a little embarrassed. It wasn’t easy for an alpha like him to show vulnerability in front of others, to admit that he had swapped battle-hardened gloves for baby wipes and burp cloths. But he loved their pups. Loved them more than he thought he could ever love anyone or anything. 

Still, his instincts as an alpha made him bristle. This wasn’t about embarrassment, not entirely. It was about being protective—too protective, maybe. The idea of anyone, even their closest friends, being too close to his family made his skin crawl. 

Katsuki grunted, running a hand through his spiky blonde hair. “Tch. Just don’t do anything stupid, got it?” he muttered, glancing over his shoulder at the group. 

Kirishima snickered but gave him a thumbs-up. “Got it, man. We’re just here to support you.” 

Izuku leaned against Katsuki’s arm, his earlier sadness melting into a soft smile. “Thank you, Kacchan.” 

Katsuki grumbled under his breath, but a faint blush crept up his neck. He couldn’t stay mad—not when Izuku smiled at him like that.

.............

They reached the school gates, where the teacher was already waiting outside, her hands folded neatly in front of her. Izuku stepped forward, his polite smile lighting up his face. 

“Good evening, sensei. Thank you for waiting for us.” 

The teacher nodded, though her expression was slightly confused as her eyes darted to the group behind them. All the students had gone home; the school grounds were eerily quiet except for the occasional rustling of leaves. 

“They are inside,” the teacher said, her gaze lingering on the unusual entourage of high schoolers. “Um, if I may ask, who are they?” 

Izuku turned to glance at his friends, who were trying their best to appear casual. “Oh, they’re our friends,” he explained with a quick, reassuring smile. 

The others chorused polite greetings, bowing slightly, and the teacher seemed satisfied enough to gesture toward the entrance. “Please, come inside.” 

Katsuki crossed his arms, his sharp gaze fixed on the door. “No need. Let’s talk here. That office is tiny. Shove all of us in there, and we’ll suffocate.” 

Izuku elbowed him sharply, sending him a subtle warning look. Katsuki huffed but didn’t budge. 

The teacher, visibly hesitant but composed, said, “Alright, if you prefer.” 

She cleared her throat before continuing, her tone professional. “Now, I must say that Mahoro and Kota are generally very well-behaved children. But today, they acted out. It’s not a major issue—the boy they hit wasn’t injured—but any form of indiscipline is unacceptable.” 

Before Izuku could respond, Katsuki’s voice cut through, sharp and defensive. “First, I’d like to know why my pups hit that brat in the first place.” 

The teacher blinked, startled by his bluntness. She straightened, her tone now tinged with polite firmness. “Bakugo-san, I would appreciate it if you didn’t use such language here. We’re in a school, after all.” 

Katsuki’s eyes narrowed, but he didn’t back down. “You don’t know the full story, do you?” 

“Kacchan, please,” Izuku interjected, his voice calm but edged with concern. He placed a hand on Katsuki’s arm, trying to ease the tension. 

But Katsuki wasn’t done. “My pups are well-behaved. They wouldn’t start something without a damn good reason. So, what did that brat do to deserve it?” 

The teacher was momentarily speechless, her professional demeanor faltering under Katsuki’s intense glare. 

Sensing the shift in atmosphere, Izuku stepped forward, his tone soft but insistent. “Sensei, I think it would be best if we heard directly from Mahoro and Kota. Could you call them, please?” 

The teacher hesitated, but then nodded. “Of course. Please wait here.” 

She soon returned with Mahoro, Katsuma, Eri, and Kota trailing behind her. The four children looked visibly distressed, their heads bowed, their small hands fidgeting nervously. Mahoro and Katsuma clung to each other, while Eri held tightly onto Kota’s arm. 

As soon as they saw Izuku, Mahoro and Katsuma ran toward him, burying their faces in his chest and bursting into tears. 

Izuku’s concern deepened as he hugged them both, his heart aching at their distress. “Why are they crying?” he snapped at the teacher, his tone uncharacteristically sharp. “What really happened?” 

The teacher hesitated, her mouth opening and closing as if searching for the right words. But before she could speak, Katsuki stepped forward, his hand resting gently on Kota’s head. 

“Kota,” he said, his tone softer than usual but firm. “Tell me exactly what happened.” 

Kota hesitated, his eyes darting nervously between Katsuki and the teacher, but the reassuring pat on his head gave him the courage to speak. 

“It started a while ago,” Kota began, his voice trembling. “There’s this boy, Daiki. He’s been bullying Katsuma for weeks… because Katsuma likes playing with Eri and Mahoro.” 

Katsuki’s jaw tightened, his fiery red eyes flashing dangerously. “And what did that little shit say?” 

Kota continued, his voice gaining strength. “Daiki kept saying Katsuma wasn’t a ‘real boy’ because he likes playing with girls. And he… he also did bad things to Eri.” 

“What do you mean, bad things?” Izuku asked gently. 

“He keeps pulling her hair,” Kota said, his fists clenching at his sides. “And when Eri told the teacher, she didn’t do anything. She just said to let it go and forgive him.” 

Izuku’s gaze snapped back to the teacher, disbelief and anger flickering in his eyes. 

“Today, Daiki tried to stick chewing gum in Eri’s hair. Katsuma tried to stop him. But Daiki pushed him to the ground. So… so Mahoro and I beat him up.” 

Katsuki straightened, his voice like steel. “And when the teacher showed up?” 

Kota hesitated, glancing at the teacher before speaking. “She didn’t listen to us. She just made us say sorry to Daiki.” 

There was a tense silence, broken only by the soft sniffles of the children. Izuku felt a sharp pang of anger rise in his chest as he pulled Mahoro and Katsuma closer, his protective instincts flaring. 

Katsuki was furious, but Izuku was even more angry. He snapped at the teacher for being so irresponsible. "First you did nothing about the bullying, then you punished my pups for fighting back. You kept them here even after school hours! They must be so hungry!" 

The commotion brought the principal outside. Izuku’s anger boiled over, and he started yelling about everything that happened. Katsuki had to intervene and calm him down. All their friends were frightened—they had never seen Izuku like this. He looked scarier than Katsuki, completely different from the sweet, smiling omega they knew. 

Izuku finally calmed down only when the principal apologized and promised to take action. 

Katsuki patted the pups. "He is scary, right?" he chuckled, looking at them. The pups giggled. 

"Prince!" Mahoro finally noticed Shoto and ran toward him. "Oi, careful!" Katsuki warned as Eri also ran to Shoto. 

"Prince, my prince!" Mahoro and Eri hugged Shoto, and Shoto hugged them back. 

"Who are these morons?" Kota asked. 

"Our classmates," Katsuki scoffed. 

The group looked confused. They thought Bakugo and Midoriya had two pups, but now there were four, and they looked nothing like their parents. What was going on? 

"Hey, Bakubro... so these are your pups, right?" Kirishima asked, looking at Kota and trying to pat him. Kota looked at him and ignored him, walking to where Katsuma was hugging Izuku. 

"Izu-ni-chan! Are you feeling alright?" Kota asked. 

"Yes." 

"Ni-chan?" everyone asked. Bakugo and Shoto looked confused. 

"Yeah? Ni-chan, so what?" Katsuki asked. They all looked at Kaminari and Sero angrily. 

"Bakubro, tell me honestly... whose pups are they? How are they connected to you and Midoriya?" Kirishima asked. 

"They are brats from the babysitting club we volunteered at during middle school. I almost ended up being arrested. Then they put me on therapy as a punishment. The club was a part of it. They're close to us even after we left the club," Katsuki explained. 

Understanding finally crossed their faces. They all turned to Sero and Kaminari. 

"Wait, guys..." they said, as Kirishima and Ida tried to grab them. They grabbed the two, and Mina started asking, "You fools... what did you hear? What were you telling us?" 

"What the frog is going on?" Katsuki screamed. 

"Frog?" Kaminari asked, confused. 

"Oh! I get it, I get it," Mina said. "It's that word... you know... the word... he can't say it because of the pups..." 

"Stop it at once. What are you talking about?" Katsuki interrupted Mina. 

Ida stepped in to explain. "So... Kaminari and Sero spied on you and Midoriya and heard you two talking about babies, so they thought that..." Ida started confidently, but trailed off. "... they thought they were your actual babies." 

"What?" Katsuki screeched. 

"Um... we thought you got Midoriya pregnant during middle school," Kirishima laughed. 

Katsuki went pale. He looked back to see if Izuku had heard, but he was busy with the pups and Shoto. 

"Lol... we almost had a heart attack thinking about that. Oh yeah, Kaminari also said that your sperm must have some superpower that you got..." Kirishima went silent after seeing the look on Katsuki's face. No, it wasn’t Katsuki’s face—it was the face of a monster.

.........

Screams echoed, and Izuku looked at where Katsuki had been, but Ida quickly covered his view. "You should not watch this, pups," he said, trying to block their sight. 

"Hey, what's going on?" Izuku asked, struggling to look past them, but Uraraka and Ida wouldn't let him. 

"Katsu-ni-chan is beating up the blond guy, the red-haired guy, and the black-haired guy..." Katsuma said innocently. 

"Did they do something bad?" Eri asked. 

"Umm... kind of..." Uraraka answered awkwardly. 

"Are they bad people?" Eri asked again, her voice full of concern. 

"No, they aren't..." Mina reassured them as she approached. 

"Why are they being beaten?" Katsuma asked, genuinely confused. 

"Aww, baby... they're getting punished for being absolute idiots," Mina said, pinching his nose lightly. 

Ida chuckled. "Actually, we all acted like idiots." 

They all laughed, leaving the pups, Izuku, and Shoto looking even more confused. 

Finally, Katsuki arrived and looked at the group. "Move," he said, and Ida, Uraraka, Mina, and Shoto quickly stepped aside. Katsuki then inspected Izuku, his eyes narrowing. "You alright?" 

Izuku nodded. "It's alright, Kacchan. I just... it reminded me of..." he trailed off, his voice soft. There was a moment of silence. 

"Sorry," Katsuki muttered in a low voice, eyes closed. 

Izuku palmed his cheeks, his smile gentle. "It's okay, Kacchan. Please don't feel guilty again. We’ve been over this, right?" 

Katsuki slowly opened his eyes and met Izuku’s gaze, his heart skipping a beat at the sight of his beautiful eyes and smile. He suddenly blushed, remembering the ridiculous assumption that he had gotten Izuku pregnant. 

"Prince, Prince, we’re hungry..." Mahoro tugged on Shoto’s sleeve. 

"Yeah, yeah..." the other pups chimed in unison. 

"I’m also craving cold soba," Shoto added. 

"We also want to go!" Kirishima, Kaminari, and Sero came over, surprisingly unharmed after the earlier chaos. 

"They’re still alive!" Kota said, amazed. 

"Yeah, we’ve become immune to your dad’s... I mean, your ni-chan’s beating," Sero grinned. 

"Actually, Bakubro didn’t beat us that bad," Kirishima chuckled. 

"Oh, Kacchan! Isn’t there a good soba place near Riku’s mama’s clinic? I haven't seen baby Riku after he started Kindergarten" Izuku asked. 

"Yeah, but it's kind of small. If all these losers are coming with us," Katsuki replied, giving the group a look. 

"You, you're actually taking us too?" Kaminari asked, his face lighting up. 

"Yeah, yeah, hurry up. We also need to drop the pups off at their home. I promised their parents I would," Katsuki said, turning to lead the way. With that, they all made their way to the soba place. 

The sun set, casting a warm golden hue over Izuku and Katsuki’s smiling faces. Their friends kept talking about how cute the pups were, but Katsuki couldn’t shake what that damn Shitty-hair had said earlier. 

"You got Izuku pregnant during middle school" 

It echoed in his mind, and Katsuki couldn’t help but flush. Why did that sound so much like the fantasies he’d had during his rut? 

Katsuki’s cheeks turned pink at the thought. 

"Kacchan?" Izuku’s gentle voice broke through his thoughts as he lightly shook him. 

"Yeah, Izuku," Katsuki muttered, shaking himself out of his reverie and refocusing on Izuku. Whatever...  He wasn’t going to dwell on it. Not now. This moment, with Izuku and their pups, was far too precious to let anything else cloud it.
