Chapter Text
Jeon Jungkook was not an easily angered person. Sure he got angry every couple of days. Who wouldn't, having a roommate that snores are loud enough to wake up satan himself or only getting three hours of sleep a night because of promotions, while having to learn new choreograph and getting bugged by the 95 line. But none of that made him angry as Kim fucking Seokjin. Beautiful, caring Seokjin. Seokjin who cooked every night for the group, Seokjin who spends hours a day trying to get down the choreography for their dance, Seokjin who has took care of him since they were trainees. Seokjin who treats him like a little brother. Seokjin who treats him like a child and not the mature alpha he is. Seokjin who most likely doesn't return the same feeling that Jungkook has had since fifth teen years old.
Sighing, quite loudly, Jungkook paused the anime that Teahyung had given him last year as a birthday present. He looked over at the kitchen. The kitchen where Seokjin and Namjoon were. Don't get Jungkook wrong. He loves all of his hyungs and only wants the best for them. But it's quite hard to be happy when your hyung is making the love of your life giggle and squeal with happiness.
Getting tired of hearing Namjoon making the omega laugh, Jungkook made his way over to the kitchen. Grabbing a glass cup and walking to the water filter, Jungkook tried to not be obvious that hew was listening to their conversation. He gripped the cool glass tighter as Seokjin squealed with delight.
"Thank you so much leader. You won't regret doing this for me."
"It's nothing Jinnie."
Jungkook gripped the counter with his other hand and tried to get his eyes to return to their normal color. Deep breaths in and out. in and out. in and out. in and ou-
"Yah, maknae what are you doing?" Namjoon's deep growl cut Jungkooks thoughts.
Opening his eyes, Jungkook saw that he had forgot to turn off the water, which was now spilling out of his glass and on to the floor. The floor that Seokjin had just cleaned for an hour. Bowing his head slightly to the eldest omega and pack alpha."I'm sorry Jinnie hyung and Namjoon hyung. I'll clean it up."
Seokin only smiled and ruffled his hair with a laugh."It's fine Jungkookie. I'll clean it up, go finish your anime."
~~~
Jungkook forced himself to not growl as he looked at the sight in front of him. Seokjin was laying on the couch wearing that ridiculously cute, over sized pink sweatshirt with only his boxers on. The only problem was who he was laying with. His Seokjin was laying in Yoongi's arms. The realistic part of his mind knew that he shouldn't get jealous at this. Yoongi is mated with Jimin and Hoseok and would never be unfaithful to them. That Seokjin is not his actual mate and could lay with anybody he wants. That it was essential for every pack to cuddle or else they get weaker and may eventually get so sick that they die. But the alpha part of his brain took over. His crush is lying with another alpha. Another alpha that has rubbed his scent all over his omega.
Forcing down another growl, Jungkook walked with heavy steps over to the unaware wolves and tried to keep his voice away from alpha command as he smacked the sleeping alpha."Yoongi. Get up now."
Seokjin just snuggled closer to Yoongi and sighed in content, unaware of the two alphas drama. Yoongi cracked an eye open and snarled at Jungkook."Don't growl at me kid."
The logical part of Jungkook knew that he shouldn't test the older alpha's patience. That he should just walk away and talk to Yoongi later about personal space, but there was no logic in Jungkook's mind when Seokjin moved his head toward Yoongi and the alpha ran his hand through the blonde locks and gave a kiss to the crown of his head. All Jungkook saw was red. Yoongi just kissed his omega.
Growling, Jungkook gripped Yoongi's thin white shirt in his hands and threw the other on the ground. Much to his dismay, Yoongi quickly got up and pushed Jungkook against the wall. Even though Yoongis appearance is smaller than all of the members, he was strong and almost the biggest when in wolf form. Jungkook looked up with angry huffs and regretted doing so. The elder was looking at him with a small smirk, mocking him. Jungkook wanted nothing more to just smack that smirk off his stupid face, and he was going to. Until he heard a small gasp and a warm hand was pulling Yoongi away from him.
"Yoongi, what are you doing to Jungkook?!"
"That little piece of shit threw me on the ground!" Yoongi was quick to defend himself, throwing his arms around Seokjin's waist and pulling him close to his chest.
"Why did you throw Yoongi on the ground, Jungkookie?" Seokjin manged to get himself out of Yoongi's hold and raised an eyebrow at Jungkook.
Jungkook blushed and stammered as he tried to think of an excuse to tell the omega."I- he snarled at me and I lost my temper. I'm sorry hyung."
Seokjin's expression softened and he turned to Yoongi. "You need to be more patient and understanding to Jungkook. He's still adjusting to the change and has a lot of testosterone in his system. He's bound to act out and be more aggressive. So you need to not test his patience and be nice to him."
Jungkook growing smirk turned in to a frown as his brain registered what Seokjin hyung said. He was treating Jungkook like a baby again. Treating Jungkook like he wasn't an alpha and that he couldn't fight. He knew that Seokjin only meant in a caring way, but it still bothered him. He wants to prove to Seokjin that he could be manly and rough even though he's the maknae.
"Let's just forget about this and go eat at a café." Seokjin grabbed both of their arms and raced out of the small dorm.
~~~
Jungkook knew that Seokjin only brought them to the café because he wanted Yoongi and him to forget the fight and act normal to each other, but Jungkook couldn't help getting angrier as time passed. Yoongi somehow manged to beat Jungkook and ended up sitting up front with Seokjin hyung in the car. He then sat right next to Seokjin in the booth, so Jungkook had to sit next to the grey haired alpha. And to top it all off, the waiter was flirting with Seokjin every chance he got. Seokjin being oblivious as usual just blushed at the mans comments and thanked him.
The waiter quickly walked over to their booth for the third time and handed their drinks to them."Here you go, one cappuccino, one latte macchiato, and one chai latte with latte art for a work of art"
Jungkook scowled as the waiter 'accidentally' touched hands with Seokjin when handing the coffee over. Looking over to his left he saw that Yoongi was also frowning, not as bad as Jungkook but still frowning. Seokjin still didn't seem to notice the angry pheromones they were releasing and continued to blush at the man.
"No need to thank me doll, I'm just telling you the truth."
Jungkook had to stop himself from puking at the man's words and tightened his grip on the table. His nails almost shifting to wolf ones. Feeling a heavy hand on his shoulder, Jungkook turned his head to see Yoongi looking at him with an understanding look. "I know it sucks to see this bastard flirting with Seokjin hyung but you need to calm down. We can't risk people finding out just because your jealous."
At that Jungkook took deep breaths and counted to three.

"Here's my number baby doll, call me sometime."
Jungkook let out a dangerous laugh, irises turning a deep red, nails gripping the table so hard making dents. "He's not going to do that, so why don't you just leave now before I kick your ass."
The man's smirk quickly fell as Jungkook glared at the man, canines threatening to come out. He gulped and practically ran to the back of the kitchen. Silence took over the booth, Jungkook almost purring in sanctification while Yoongi looks annoyed but not as tense as before and poor Seokjin looked confused.
"What was that Jungkook?"
Jungkook's eyes popped opened at the tone of the omega's voice. He sounded upset with Jungkook but Jungkook can't understand why. He did his duty as an alpha of the pack, protect and keep away all danger, but Seokjin didn't seem to like that.
"What's wrong hyung?"
"You just threatened that poor, innocent man. Kookie, you need to know how to control yourself and not lash out on every person that does something you don't like."
"He was bothering you hyung. He could have been a crazy ax lunatic or rapist! You can't trust everyone hyung, people will take advantage of that and I really don't want that to happen." Jungkook's voice wavered toward the end.
Seokjin only sighed and ruffled his hair with a smile. "You're too protective for your own good, Kookie."
~~~
Jungkook tightened his hold on the blanket as he thought back to the conversation that he had ease dropped on.
"What do you think of Jungkook, hyung?"
"What do you mean Yoongi?"
"I'm saying that the kid is in love with you and you need to get over that he's younger and just admit your feelings too."
"He's too young, Yoongi. He's going to realize that he can get anyone he wants and will dump me for some young omega his age." Seokjin's voice cracked at the last part and Jungkook so badly wanted to make his worries go away but his feet were glued to the floor.
"The kid has been in love with you since we were trainees, hyung. I don't get how you just realized his crush on you a month ago." Yoongi chuckled before continuing, "He loves you and trust me, he would never dump you unless it was a life or death situation. He's waited for you for more than three years, I'm sure if it was just a little crush, he would of stopped chasing after you years ago."
Jungkook was tired. He was tired of Seokjin treating him like a child. Tired of hiding his love for the elder. Tired of other people hugging and flirting with his omega. Tired of not being able to hold the other in his arms. Tired of not being taken seriously. Tired of not being able to show Seokjin who's boss. He was just done it with all, tonight he is going to show Seokjin that he's the alpha. That he's not a child and can tease the elder until he was a pile of goo begging for more.
~~~
Jungkook sauntered his way to Seokjin and Yoongi's room and quietly opened the door. The rapper was out, most likely at the studio writting more songs. Seokjin was laying on his bed, white t-shirt that showed off his beautiful collar bones and pink boxers that made his ass look even more delightful. Jungkook took the chance while the elder was discracted and pounced.
