For mochijiminhasjams
Thanks for the request 💙

Jungkook and (Y/N) have known each other since they were little. They always played with each other and went to the same elementary, middle school and now they were in the 2nd year of high school.
But there is something that these two friends were hiding from each other and from the rest of the world, it is dark and twisted. And one day it was bound to be found out.

"Jungkookie!" A senior,Jimin, squealed and hugged the taller boy.
The boy blushed a little and looked at him.
"H-hi hyung, did you need something?"
"Not really,just wanted to ask you and
(Y/N) to have lunch with Tae and I."
Said girl was fuming while looking at the two boys.
'Get away from my Jungkook, Park!'
She thought,but said es anyways.
"Sure."
Jimin grinned and took Jungkook's hand, dragging him away.
'You are dead Park! He is mine!'
(Y/N) then walked after them, let's just say that nobody dared to speak to her, that's how scary she looked.
Meanwhile, Jungkook was looking in confusion at his hyung, having noticed how clingy Jimin had been these past few weeks, but then shrugged it off.
'Well, hyung can be strange sometimes.'

During lunch (Y/N) was sitting with Taehyung and across from them were Jimin and Jungkook.
The older boy was hugging the taller ones arm. Jungkook wasn't paying much attention to it, Taehyung on the other hand was shaking in fear, considering that he could feel the anger radiating from
(Y/N).
'Jimin, you are playing with fire...'
'Mine, mine,mine! Jungkook is mine!'
(Y/N) thought while mentally stabbing Jimin.
Lunch went on like that, when the bell rang the four went in different directions.
Taehyung sighed in relief and Jimin looked at him in confusion.
"Why were you nervous so much during lunch?"
"Couldn't you feel (Y/N)'s anger? This isn't a good idea Jimin, I'm worried for you."
Jimin giggled and kissed Taehyung on the cheek, who only blushed at that.
"Don't worry dear, in no time the two will be together. By the way, you looked jealous a little, hmmm."
Taehyung rolled his eyes and took Jimin's hand into his.
"Well seeing your boyfriend being clingy with someone else."
"Cute~"

That same night, (Y/N) was walking towards Jimin's house. She was dressed in black and had her father's gun in her backpack.
"I will finally get rid of you. And then Jungkook will be mine only, forever~"
(Y/N) giggled like a maniac when she arrived in front of Jimin's house.
She started to pick his lock and in mo time unlocked it. Quietly she walked around the house, trying to find her rivals room.
Then she opened one door and found Jimin sleeping peacefully in his bed.
'Aww so cute... He makes me sick!'
(Y/N) took out the gun and a pillow from her backpack. She put the pillow on his face and shot him.
Blood started to come out of his head and (Y/N) grinned.
'Finally he is gone.' She took her stuff and quickly ran out of his room.

The next day, everyone was just depressed. Word got out that Jimin was killed and everybody was in disbelief. He was such a nice and sweet guy. But Taehyung was the worst, he left school after the first period after he broke down in uncontrolable sobs.
(Y/N) didn't care that much about it, her attention was purely on Jungkook the whole day.
During lunch they were behind the school, eating and talking.
"Hey... umm (Y/N) I wanted to ask you something."
"What is it Kookie?"
"I... I really like you (Y/N)... Do you want to be my girlfriend?"
(Y/N)'s eyes widened and smiled brightly, then she kissed Jungkook.
"I would love too!Also I love you too."
Jungkook grinned and the two kissed.

The two had been dating for two months and they couldn't be happier. The two are also very protective of each other.
If a girl dared to flirt with Jungkook,(Y/N) would threaten the girl with a knife.
Jungkook on the other hand would beat any guy who dared to look at (Y/N) the wrong way.
But one day something happened that changed their lives.
Jungkook was walking towards the rooftop to meet (Y/N).
'My sweet (Y/N)... She is only mine, why don't these guys understand that and leave her alone?!' He thought while glaring at the floor.
Then he heard two voices... a boy's voice and... (Y/N)?
Jungkook's blood boiled and fists clenched.
'Who dares to talk to her?!'
He found the two in an abandoned classroom. Namjoon was pinning (Y/N) against the wall, while said girl glared up at him.
"So what do you say,(Y/N)? You, me and the movies on friday?"
"I rather not. Leave me alone now, I need to meet up with Jungkook."
"C'mon princess, don't be like that."
Jungkook walked into the classroom silently and took out his knife. He walked up behind Namjoon and sliced his throat.
Namjoon fell to the floor,dead, and (Y/N) looked at Jungkook in shock.
"Jungkook..."
"I'm sorry that you had to see this... But I don't like other people touching you..."
Jungkook looked down,but (Y/N) lifted his head up and kissed him.
"I... I have to admit something too... I was the one who killed Jimin... He was too close to you.
Jungkook chuckled and hugged his girlfriend.
"Seems like we are the same... How about we run away... Let's leave Seoul, together."
(Y/N) smiled and nodded.
"Sounds great. Let's go."
With that the two teenagers ran off, never to be seen by their families or friends.
