Katsuki hadn’t shared a bed with anyone since he was four years old. He honestly thought it would be awkward to have someone so close to him all night long, especially because he’s such a light sleeper.

Still, nothing of that had mattered when he suggested Tenya to spend the night at his room, and after a long argument why they wouldn’t get caught if they got up early as usual for their morning jog, he was more than happy to get his boyfriend to stay.

As it turned out, it had been one of the best nights in Katsuki’s life. Proof of that was that he felt pure bliss as he woke up with his face pressed against his boyfriend’s chest.

He lazily turned his head just enough to look over the broad chest and stare at his digital alarm clock.

7:54

Katsuki blinked.

7:54

He rubbed his eyes.

7:55

“Fuck!” Katsuki yelled just as he sat on his bed and began shaking his still sleeping boyfriend. “Wake the fuck up right this fucking moment!”

The class representative groaned, his grip on the other boy’s waist tightened and he buried his head on the pillow. “What’s wrong?”

“We’re running late for class!”

That got the taller boy’s attention, and he finally fully woke up, sitting on the bed as well, searching for the clock on the nightstand.

“Shit.”

Shit indeed. Katsuki thought, not even having enough mind to relish in the fact that his boyfriend had cursed, thing that happened so rarely that it was almost like seeing a shooting star.

Without wasting any more time, they both scrambled around the room to get dressed. Later, once this becomes a funny story, he would tell Tenya that he had been right in telling him to bring his uniform just in case they decided to skip their morning jog.

“Fuck, fuck, fuck…” the blond kept muttering like a chant as he grabbed both uniforms from his closet and handed Tenya his. “I don’t understand what the fuck happened with my alarm. Must be broken.”

Tenya hopped into his pants to pull them up in one swift motion. “I’ll tell Hatsume-san to have a look at it in the afternoon. But it’s weird that I heard it the first time…”

Katsuki stopped halfway through buttoning his shirt. He turned to look dead in the face at the other boy. “The fuck do you mean by the first time?”

“I mean, I heard the first alarm and I turned it off, but the following ones didn’t rang”, he explained a little confused.

“What other two?!” he yelled angrily. “I only have one and that’s usually enough to wake me up!”

“I-I… I thought…” Tenya opened his eyes wide in shock as the realization suddenly hit him. “Well, this wouldn’t be happening If you hadn’t insisted on me spending the night!”

He gasped indignant, fury clouding his mind. “Well, fucking forgive me for wanting to cuddle!”

“You could have waited for the weekend to plan a sleepover!”

The blond stood silently, probably thinking what else to reply, but they didn’t even had time to argue, the clock on the nightstand already read 5:58 and they still had to get to their class or they’ll both put their perfect assistance at risk.

He hung his blazer over his shoulder and walked closer to his boyfriend.

“After school I’ll make you see this is your fault for being a freak with multiple alarms, but right now I need you to use your quirk to get us to class”, he ordered standing face to face with him.

“We can’t use quirks out of class while in the campus!”

The boy looked so undignified it was almost funny.

“Do you want to be late then?”

Tenya seemed to think for a moment with his mouth wide open, but once he understood it was their only option, he handed Bakugou his own blazer. “Just for the record, having multiple alarms is way more common than having just one”, he huffed and then picked the blond up in a bridal style.

After that, Katsuki didn’t have time to reply, because it took his boyfriend slightly less than a minute to get them both to a couple steps before the front door of their class.

“Thank you”, he said once Tenya came to a stop, rapidly looking away with a light blush, hoping that no one had seen them.

Tenya gave him a quick kiss on the cheek and then winked once at the blond who turned his head to face him with a blush more noticeable than before. “You’re welcome.”

“Dazzling idiot…” he muttered lowly.

Tenya looked like he wanted to say something else, but the bell rang at that moment announcing the beginning of the school day.

Katsuki practically jumped to the ground and handed the boy his blazer. Both of them trotted towards their class while putting their blazers on.

“Sorry for the delay!” Announced Tenya as soon as he slid the door open and then bowed. “May I come in?”

“Sorry, sensei. I overslept”, Katsuki said nonchalantly, arriving just a couple seconds after the class representative to not make it too obvious that they had both arrived together.

As soon as he finished speaking, there were a couple snickers in the room and some mutters. The two boys who always arrived first got here late, so what? It wasn’t enough reason for a reaction like that, Katsuki thought with a frown.

Mr. Aizawa looked at the two of them from head to toe with an expression that seemed more tired than usual.

“What about you, Iida? Did you oversleep as well?” He questioned with an arched brow that somehow looked even more exhausted.

“I… Uh… Yeah…” The boy answered confused about the question and he instinctively reached out for his own hair to placate it. “I’m afraid I got too hung up with… a book. I failed to wake up early this morning and just as I was running this way, I happened to cross paths with Bakugou.”

Katsuki had to bite the inside of his cheek to stop the smile that desperately wanted to form on his lips as soon as his boyfriend lied about what had kept him up so late last night.

“And what about you, problem child?” he turned to silently judge Katsuki now. “What was the reason you failed to wake up early?”

Now that was odd. Their teacher hardly ever showed interest about their lives unless there was something fishy going on, which in this time happened to be the case. The guide of conduct said they weren’t allowed to sleep in the opposite sex wing of the dorms, so technically they weren’t breaking any rule. They were, however, doing the thing why that rule probably existed in the first place.

“My alarm ran out of batteries during the night”, he lied way more convincingly than Iida. But a look at his teacher’s stern gaze told him he wasn’t buying it.

The man stayed silent for a long while after that, causing the murmurs of his classmates to increase. Eventually, the teacher sighed and motioned with his head that they could come inside.

“You may come in”, both boys began walking as soon as they were granted permission, thinking that they had gotten away with it. “But Iida, I suggest you get a new blazer since yours seems to have shrunken in the washing machine…” Katsuki stopped dead on his tracks and turned his head so fast he got whiplash, but that didn’t matter, because it suddenly hit him that Tenya’s school jacket looked oddly tight on his shoulders. The boy seemed to realize the same thing and looked alarmed at him and then back at his teacher. “Or perhaps you could switch with Bakugou, since his seemed to have somehow gotten bigger.”

The snickers got louder, and he could finally understand his classmate’s reaction. They had been caught in the lie before they had even said it.

Katsuki closed his eyes with shame, and he felt his cheeks grow warmer. He would need a lot of threatening to stop the extra’s from ever speaking of this.

“They must have been swapped in the laundry room by accident”, Tenya tried to push their lie.

“I’m sure that’s what happened”, the teacher gave them both a knowing look. “I want you two to stay after class for a very serious conversation.”

“Yes, sensei.” They both said in unison before taking off their blazers and sitting on their respective seats.

“Someone’s getting the talk”, Kaminari teased loud enough for everyone in the room to hear it and it was followed by another round of snickers.

What was even worse was that Mr. Aizawa didn’t deny it.

Katsuki groaned and made himself smaller in his seat, as he was sure his boyfriend did the same. Lamenting what was probably the beginning of a new set of rules just for the two of them.
