A/N: idea @Mehreen_uz55

"Hyung!" Jimin runs behind Jungkook as they played

The 10 year old stops running making the 5 year old Jimin crash into him

"Ahh Hyung! Why did you stop?" Jimin pouts

Jungkook turns around

"Didn't I tell you to stop calling me hyung?!" Jungkook's glares make Jimin teary eyed

"I'm sorry Kookie..." the tiny boy looks down

"Good..." Jungkook smirks, "...that's like my good baby boy..."

Mr Jeon and Mr Park were the best of friends and whenever they visited each other, their kids hung out together. Jungkook always had a cold personality, maybe because his mother left his dad for another man, but whenever he met Jimin, his playful side came out- that is if Jimin obeyed him without questioning, which the tiny boy did - he liked the elder boy being protective of him

**

A couple of years later, when Jimin is 13 years old, his dad passes away. He had already lost his mother in childbirth and so Mr Jeon takes it upon himself to take in the boy legally as his own son. He thought Jungkook would be happy about it, seeing that the boy would only smile for Jimin

Sadly he was wrong

"Jimin will live with us from now on" Mr Jeon says making Jungkook very happy

"Really dad?!" The 18 year old had a sparkle in his eyes

"Yes... so you better be a good elder brother to him..." Mr Jeon smiles, pulling Jimin to his side- Jungkook's smile fades "...I already legally adopted him... so Jiminah... Jungkook is your hyung from today"

Jungkook fumed

"He will never be my brother! Did you get me?!" Jungkook throws the vase next to him on the floor, shattering it to pieces

Jimin tears up - does Kookie hate me?

"What kind of behavior is this Jungkook?!" Mr Jeon fumed at the boy who walked away from them "...he is a Jeon now... you better accept that!"

Jeon huh... Jeon Jimin... of course he will be.. but not as my brother...- Jungkook smirks

**

Jungkook talked to Jimin only if the boy addressed him as Kookie. Jungkook stopped talking to his dad, he was angry but Jimin's presence calmed him.

Jungkook was waiting for Jimin to be 18 so that he could legally make the boy his.

**

Jungkook's dad didn't like Jungkook's vibe and so he tried to get Jimin away from his son as much as possible, but of course it was in vain - Jungkook knew how to manipulate Jimin's innocent mind

Jimin didn't find it too odd because Jungkook was always protective and a bit possessive of him. Jimin felt safe.

Mr Jeon decides to get Jimin married as soon as he was an adult. He feared for Jimin's life in the hands of his son - the Jeon mafia king

**

Jungkook was angry. He tore down the place when he heard Jimin agreed to marry A/N.

You shouldn't have done that, baby boy. You provoked the devil within me.

Jungkook was in Daegu when he heard the news. He wasn't invited to the wedding, it was to be a private secret marriage signing.

Jungkook flew back home immediately.

"You didn't think it necessary to inform me of Jimin's wedding?!" He fumes at his dad

"Y-You were busy in a mission. Besides it's not a big ceremony..." Mr Jeon struggles to speak as Jungkook choked him

"But how could the wedding take place without the groom?" Jungkook tilts his head at his dad

"W-What do you mean?"

"Me... of course... I'm the groom" Jungkook smirks before choking his dad further

**

Jimin was sleeping peacefully in his room. He gets woken up when he feels a presence behind him on his bed. He panics

"Shh... it's me..." Jimin calms down a bit when he realises that it was Jungkook

"When did you get here Kookie?"

"Just now. Why didn't you tell me you were getting married?" Jungkook looks at him intently

"Appa told me you are on a mission and you couldn't come..." Jimin pouts

Jungkook curses - that bstrd

"So you wanted me to come?"

"Of course..." Jimin smiles

Jungkook couldn't help but lean in to kiss that rosy lips

"W-What are you doing?" Jimin leans back, avoiding the kiss

Jungkook fumes "Won't you kiss your husband, my dear wifey?"

Jimin's heart beat quickens "W-What?"

"Fcking beach!" Jungkook grabs hold of Jimin's neck, scaring him "...how dare you plan to marry someone when you belong to me?! You are my property! Jeon Jungkook's property!"

Jimin's eyes widen and before he knows it Jungkook is roughly kissing him, the man's hands feeling up his body

"S-Stop... p-please..." Jimin says pushing the man weakly. He was paralyzed with fear

"How dare you push me away?!" Jungkook is angry "..after everything I did for you... you are so ungrateful... so disrespectful of my love for you..."

Jimin pushes Jungkook and gets up from the bed

"What are you saying Kookie... I'm your brother..." Jimin walks backwards

"Adoptive brother..." Jungkook stalks towards the boy "...and I don't see you as my brother" Jungkook slams his hands on the wall, trapping Jimin between his arms

Jimin gets scared

"Appa!"

Jungkook chuckles darkly "No one can save you from me! I killed him! I killed A/N too. I killed everyone who looked at you with their dirty eyes..."

Jimin is scared, his tears stream down his cheeks. Jimin remembers the time Jungkook came to his school to beat up the kids who bullied him, he remembers how they disappeared suddenly. He also remembers how the guys who confessed to him, suddenly transferred school. He didn't need to know that Jungkook had murdered them as well.

"You are my princess ..my queen... my baby boy..." Jungkook licks Jimin's ears making him flinch in disgust "....you are mine to keep... mine to ruin... mine to save... mine to fck..." Jungkook drags Jimin to the bed, despite Jimin's struggles "...and believe me I'm gonna fck you... every hour, every minute, every second... night after night... I will be fcking you right.... fcking you till all you can think about is me..."

Jungkook throws a scared Jimin onto the bed

"I will never love you! You can't force me!"

Jungkook chuckles at Jimin's cute struggles. Jimin's punches felt like a cute kitten jumping on him.

Jungkook's eyes so soft "Oh honey... I don't care if you love me or not... because I love you for the both of us..." Jungkook puts his entire weight on the tiny boy, effectively pinning him to the bed "...I could never hurt you...but trust me..." Jungkook's eyes suddenly darken "...if you try to escape ... you will see the dead body of the next person you see ....just like my first victim... your lovely dad who refused to give you to me "

Jungkook says before ripping off Jimin's clothes

That night Jungkook claimed Jimin completely as his - in every sense

**

"Wait... are you saying that Jungkook was the one who killed Jimin's dad?"

Taehyung nods

"Wow... that Jungkook character is a pyscho.... he is so sexy though... his entire vibe in the movie is so hawt... his obsession and passion for Jimin is on another level..." Jimin comments making Jungkook frown

"What do you mean Jungkook is sexy and hawt?" Jungkook mocks in sarcasm "...What about your husband who is sitting right here?"

"You are...meh!..." Jimin says looking at Jungkook " ..but that Jungkook... with the lip piercings and tattoos.. so hawt..." Jimin says looking at the screen, nearly drooling

Jungkook stands up "..Taehyung... I think its time for you to leave..."

Taehyung chuckles getting up "...I'm guessing you didn't like this psycho movie..."

"Oh I did... but I am not liking my husband liking it too much... he needs to be taught a lesson.."

"Good luck chim"

Taehyung walks out making Jimin nervously chuckle

"Jungkook... you know I was just teasing right?" Jimin says as he sees Jungkook walking towards him

Jungkook smiles slightly as he caresses the boy's face "Of course I do..."

Jimin sighs in relief but before he knows it, Jungkook has thrown him over his shoulders

"But you still need to be reminded of who you belong to" Jungkook says smacking Jimin's ass
