"young master please don't do that or your mother would be furious" Hyerin said as she tried to convince Jungkook who was up the tree and refuses to go down, "tsk...leave me alone!" Jungkook yelled, Hyerin could only sigh when she heard a clicking noise coming their way, Hyerin turn around and immediately bow down to see Jungkook's mother.

Jungkook glared at his own mother and look away, "Who's that..." Jungkook said pointing at the calm young boy beside his mother, "Jungkook meet Taehyung, Taehyung meet Junkook..." The mother expected them to shake hands or even say hello but that was impossible for both Jungkook and Taehyung since both shared a deadly glare on to eachother.

"I don't like you, get out of my face." Jungkook said causing his mother to gasp and so did Hyerin, "Young master! why wou-" Hyerin was caught off when Taehyung let go of the mother's hand and look at Jungkook.

"What a coincedence, I don't like you either." Taehyung said and Hyerin could only faint at the sight of the two step brothers already hating eachother, The mother sigh. "Please do get along because I won't always be here to take care of you..." She said, Jungkook roll his eyes and climb down the tree dusting himself off.

"You weren't here to take care of me properly from the start" Jungkook said and ran away, Hyerin woke up from her sudden faint and gasp again, "Young master!!!" Hyerin yelled.

The mother sigh and knelt down at the size of Taehyung, "Jungkook is a nice boy but he just have mental problems...he tends to hate people just by their existence...that's also the reason he hates me too..." She said slightly taking in the pain to what Jungkook said to her.

Taehyung could only nod and wave at her goodbye as she left for another business trip, Jimin walk around the garden to find Taehyung standing alone and was curious of him. "Hello...m-m-my name's...Jimin" Jimin shyly approached Taehyung but he soon back away when Taehyung was holding a dead bird with blood in his hands, Taehyung glance at Jimin and smile. "the bird was about to die...and I wanted to watch him die but it was taking too long! So! Hahaha! I helped the little birdy to go to heaven!!!" Taehyung exclaimed and it sent shivers down to Jimin's spine thinking what kind of kid was he?

"your name's Jimin right! I'm Taehyung! pleased to meet ya!" Taehyung drop the bird and without noticing he step on the bird's head and it made Jimin scared and back away.

"y-yeah....I-I'll see you later..." Jimin mumble and run away.

------------

Jungkook was on his secret hide out with a plate filled with bird food, "Cooky? where are you???" Jungkook checked every area to find it gone, He sigh and decided to check the garden.

Jungkook search the area until he found something on the ground and he couldn't even be more terrified than to find his bird's head crushed, He drop the plate of food and knelt down..."Cooky....why...why are you like this...wh-who did this to you...." Jungkook said and pick the bird's head and body, He cried and cried during that night and he couldn't stop until he was on his bed.

Jimin peek through the door to see Jungkook making soft cries, He went inside his room and tap his shoulders...even if Jungkook didn't like him that much Jimin still believe he will look st him as a brother, Jubgkook felt Jimin's touch and look at him.

"What is it you want" Jungkook coldly said and glared at Jimin, He gulp. "I know who killed Cooky..." Jimin said earning Jungkook's full attention, "Who is it..." He demanded Jimin.

"It...it was Taehyung...." Jimin stuttered but the next thing he knew that Jungkook was gone and was marching his way towards Taehyung's room.

Jimin run after Jungkook and covered his mouth when the two were fighting, Jungkook was more furious than ever that he tried to hit him with a vase, "YOU KILLED MY BIRD!!! YOU PYSCHO!!!" Jungkook yelled and Taehyung could only laugh even though his nose is bleeding bad.

Jimin trembled in fear, he tried to stop them but he couldn't and so he called for help that's when the maids and the butler came running up the stairs and seperate both Jungkook and Taehyung.

"Taehyung! your nose..." Hyerin said and tried wiping it but her hands were slap away by him, "Do not touch me woman" Taehyung glared at her, Jungkook click his tongue. "Your bird was about to die anyways...and it would be nice to hear a thank you" Taehyung said earning a growl from Jungkook, he push the man away and grab him by his collar shirt.

"I despise you the most"

Jungkook then left and proceed his way back inside his room, Taehyung smirk, "let's see about that" He thought and entered his room.

-----------------

"hey, hey have you heard?"

"about what?"

"There was a new student next to our class, heard his really hot!"

Jungkook wanted to rip their mouths off when they were talking about Taehyung who killed his bird, "fuckin whores" Jungkook thought and stood up from his seat and left his classroom in silence.

Jungkook walk down the hallways only to notice Jimin struggling to get up, "you alright..." Jungkook said appearing infront of him, Jimin sigh and nod. "yeah...just fine..." Jimin said his smile turn into a frown and tried to hid the bruise in his arm but it was too late for it to be hidden when Jungkook caught a glimpse of it.

Jungkook then rolled up Jimin's sleeve to see a big bruise, "Who did this to you?" Jungkook ask but to Jimin he stayed silent, Jungkook click his tongue. "It was him right?" Jungkook said and Jimin could only nod.

He gritted his teeth, "go to the infirmirary...I'll go talk to that bastard" Jungkook growled and left Jimin worried.

It didn't take a minute to find Taehyung when he was surrounded by girls and it only made Jungkook irritated because of their screams.

"oppa! where are you from?"

"you look like an anime character!!!"

"look at that jawline!!!"

"YOUR HOT!!!!"

"now, now, ladies you don't want to get in trouble for being too noisy and yes I do look like a anime character..." Taehyung said showing off his face even more, Jungkook growled.

"What a shit"

Jungkook said out loud causing everyone to look at him in shock, "It's Jungkook oppa..." One of them said and they all hurriedly left because of fear, Taehyung smirk. "so...their scared of you?" Taehyung said but Jungkook continued to glare at him.

"you prick...you hurt Jimin" Jungkook said clenching his fist, Taehyung laugh. "the guy was weak and too slow to catch up....that is why I am going to use him as my toy~" Taehyung said smirking even more wider watching in delight to see Jungkook angry.

"are yoy angry now Kookie?" Taehyung said and lifted his chin.

"do you want to kill me?"

From that moment something or someone pushed his button that he never knew existed, it made him feel want to kill, torture, and be more superior than anyone.

Jungkook grip on his wrist and looked up at him, it gave Taehyung a shiver.

"Yes...I want to kill you so bad and torture you...I'll pull your eyes out of your socket and feed them to you"

Jungkook said to him and left.

"That's good then Jungkook! I'll wait for you to kill me~"

-------------

Many years had pass and still Jungkook hated Taehyung in every bit of his existence and wanted him gone for good, Jungkook turn quite matured for his age at 17 and for Taehyung he had grown to be a fine young men that everyone thought of him.

"what's with all this dinner and shits" Jungkook mumble trying to remove the necktie that was around his neck area.

"are you alright?"

Jungkook growl, "obviously not! I can't loosen this necktie up" Jungkook complaine and face the person who approach him but at that moment his heart came back alive as if he was healed right away.

"then, let me help you...but I'm no expert at doing neckties because I prefer turtle necks" The man said right infront of him, a blush made it's way to his cheeks and could only stare at the beauty infront of him.

"There all done! Wow not bad" He said fixing Jungkook's collar shirt, "w-what's your name..." He ask, He glance at him and giggled.

"my name is Kim Seokjin but my friends calls me Jin! but your free to use that nickname" Seokjin said wirh a thumbs up.

Jungkook blush again and smile, the smile he never thought exist in his face.

"and I'm Jung-"

"Seokjin where are you???"

Before Jungkook could say his name, they were caught off by a man who happens to be Seokjin's father, "My dad's here! I'll talk to you later then" Seokjin said and wave goodbye to him.

Jungkook was upset when he only knew about his name and not all of him but he did follow Seokjin from behind and they ended up at the dining table, Jungkook watch from afar from an open door to see Seokjin introducing himself.

Jungkook glared at Taehyung who stood up and shook hands with him, He thought he was the only one who changed...guess he was wrong...because the person who also changed was none other than Taehyung.

---------(5 years later)----------

It's been five years since Seokjin and Taehyung got married and it broke Jungkook's heart when he couldn't even do anything but to watch them pledge their vows, Jungkook grew even more stronger and still plans to get his never ending revenge to Taehyung...and his possession over Seokjin grew.

"What did you find?" Jungkook ask Rose who placed a envelop on his table, "this happened three years ago...and until now..."Rose said Jungkook raise his brow and open the envelop...he couldn't handle to what he saw.

"HIS CHEATING BEHIND SEOKJIN!!!"

Jungkook yelled startling Rose, "Yes...and I believe that Mr. Seokjin knows about it too...because he hired someone to watch over Mr. Taehyung..." Rose said earning a growl from Jungkook.

"leave"

Rose nod and left his office, Jungkook lean on his arm chair and sigh.

"It's time to get back what's mine...."
