Taehyung’S Forbidden Stranger
Jeon's Heir
The sky wasn’t just dark—it was furious.
Thunder cracked like bones breaking, echoing across the hills.
Rain didn’t fall—it attacked, lashing against the windows of the mansion like a warning from the heavens.
Inside the grand, dimly lit room, the air was heavy—thick with pain, fear, and something far colder… purpose.
A woman lay on the bed, her face pale, drenched in sweat, eyes wide with pain—but not just from childbirth.
From something deeper.
Something she couldn’t name.
The walls of the mansion didn’t echo with love or comfort.
Only silence.
A silence so loud it screamed.
This wasn’t just a birth.
It was a prophecy. The Legacy of Jeons.
Miss. Shin ( Doctor)
push! You're almost there!
Jeon Mira
(screaming) I-I can't--!
Jeon Daewoon
You can Mira. You must ( His voice was sharp. unshaken, without any feelings)
Jeon daewoon: His hands didn't tremble upon seeing his wife in pain. he didn't whisper comforting words.
To him, pain was necessary. Suffering-inevitable.
Miss. Shin ( Doctor)
yes! yes, Mrs. Jeon just one. we can see baby's head.
and then they heard a cry--
Not soft. Not innocent
but loud. Strong. Defiant.
Like the child knew the world he was born into- and hated it already
Miss. Shin ( Doctor)
it's a boy ( she said happily)
Miss. Shin ( Doctor)
He's healty and Strong, Mr and Mrs. Jeon
The woman, Mrs. Jeon sobbed—not from relief, but from something far more terrifying.
She had brought a life into the world…
But she knew deep down—
This was not a normal life.
This was something darker.
Sharper.
Colder.
Jeon Daewoon
( steps forward, holding the child and said loud and clearly)
he will not feel weakness
he will not crave love
he will not beg for mercy
( there was no love, warmth in Daewoon eyes)
Jeon Mira
( weeping softly) Daewoon.. he's our child. He's my innocent baby. Please don't do this
Jeon Daewoon
No. He is my legacy. The heir to the underworld ( he said firmly and sharply while looking at his wife)
Jeon Daewoon
( He looked at Miss. Shin Sharply and said- his voice low, threatening)
This child..He doesn't exist to the world. If a single whisper escapes these walls ( pauses, locking eyes with her)
-- I will bury you. Alive
Your family
your Bloodline
The doctor’s hands trembled. Her throat dried.
She had seen death before.
But never in the eyes of someone holding new life.
Miss. Shin ( Doctor)
( bowing deeply)
I- I understand. I swear. No one will know. I'll take it to my grave, Mr. Jeon
Jeon Daewoon didn't blink nor looked at her.
He just turned his back, cradling the child like a king holding a crown
Or a Curse
The child cried again.
Not with the wail of a newborn—
But with a strange intensity, like his soul already knew the cruelty of the world he had entered.
Mira’s heart clenched.
Jeon Mira
(voice trembling)
Please… give him to me.
He needs me. He must be hungry. He needs his mother’s warmth… my love…
Daewoon stared down at the child in his arms.
For a moment, there was a silence so thick it nearly suffocated the room.
Then, slowly, he placed the baby in Mira’s arms.
But his voice was colder than the thunder outside.
Jeon Daewoon
He doesn’t need your love, Mira.
Nor your warmth.
He will rule the underworld—
And I won’t let you turn him into a weakling.
(steps closer, voice dropping to a deadly whisper)
If you dare… even once…
to soften him—
You will lose the right to hold him.
To see him.
Forever.
Daewoon turned without another word and walked out of the room, his footsteps heavy with pride and power.
The door clicked shut behind him, sealing Mira in silence.
She looked down at the tiny child in her arms—so small, so unaware of the fate that had already been written for him.
Jeon Mira
(whispers, voice soft but firm)
Never…
I will never let you become a monster like him, my love.
I don’t care what your father says…
You’re mine. My baby. And I will protect your soul.
She held him close, placing him to her chest.
The child quieted, comforted by her warmth—the only warmth he had ever known.
He fed slowly, little fingers curling into her gown.
And when sleep took him, Mira let it take her too.
No maids came to help.
No guards dared offer comfort.
She was alone.
She had loved Daewoon once—with every part of her heart.
And deep down, she still knew he loved her too…
But his hunger for power had devoured the man she married.
Blinded him.
Twisted his love into ambition.
In the grand marble hall below, Daewoon stood like a shadow cut from the storm itself.
His black coat dripped with rainwater, but he looked untouchable.
Unshaken.
Maids lined the walls.
Guards stood with heads bowed.
Every servant, every loyal hand in the mansion was gathered—silent, obedient, trembling.
Daewoon raised his hand.
Jeon Daewoon
The heir to the throne is born.
My blood.
Your future king.
Jeon Jungkook…
My heir.
No one dared to speak.
No one dared to breathe.
Thunder cracked again—
As if the world itself had just heard his name.
Bodyguards
All hail the heir!
Long live Jeon Jungkook!
The future king of the underworld!
Staffs/ Maids
All hail the heir!
Long live Jeon Jungkook!
The future king of the underworld!
Their voices echoed like a war chant—
Loud, loyal… and laced with fear.
Not one of them dared lift their eyes to Daewoon.
Not one dared show hesitation.
They knew what disobedience meant in this house.
They had seen it.
Buried it.
A Caged Childhood
Jeon Jungkook was now one year old.
He had just taken his first steps.
But there was no celebration. No warmth.
Only silence... and control.
Mrs. Jeon was kneeling on the floor with her hands open wide
Jeon Mira
come on my baby.. come to mama
That's it, baby... Just one more step! ( she was smiling widely while looking at her son)
Jungkook took a shaky step forward, then another.
His eyes lit up at his mother’s smile.
He stretched his tiny arms out, heart racing with joy.
Jeon Mira
That's my boy! you're walking! ( she said with teary eyed)
But before she could catch him in a hug--
Jeon Daewoon
step back, Mira ( sharp voice)
Jeon Mira
Daewoon... let me hold him. just for a moment, please (pleading)
Jeon Daewoon
Enough. He's not a toy to cuddle when he amuses you ( cold gaze)
Jeon Mira
He's not a weapon either (cold gaze)
Meanwhile, Jungkook stumbled and fell. He began to cry softly.
Mira moved quickly to pick him up, but Daewoon was faster.
Jeon Daewoon
Stop crying.
Crying is weakness. There is no room for it in your blood ( picking up Jungkook)
Jeon Mira
(voice trembling) Daewoon.... He's just a baby...
Jeon Daewoon
(firm) He is the heir to the underworld. He doesn't have the luxury of being "Just a baby".
Jungkook clung to his father’s black shirt, sobbing silently.
His little eyes looked over Daewoon’s shoulder—toward Mira.
Jeon Mira
(voice breaking) Please... at least let him be held by his mother. He needs warmth.
Jeon Daewoon
(turning away) The world is not warm, Mira. He'll learn that early.
saying that daewoon left with jungkook leaving Mira alone to cry.
~Time skip:- Afternoon at Private training room~
The mansion had a room no maid dared enter.
It was Daewoon’s training space—soundproof, sealed, and strict.
Bodyguard 1
( whispering to another) He's really going to start training the baby.
Bodyguard 2
He's not a baby. Not in Master's eyes.
Jungkook sat in the middle of the floor, surrounded by wooden blocks—not for play, but for testing focus.
Jeon Daewoon
(standing over Jungkook) Pick up the block.
Now place it in a straight line. No mistake.
Jeon jungkook
( confused, staring) Ba...bwoo..?
Jeon Daewoon
(snap fingers) Don't babble. Just focus, Jungkook
Jeon Mira
( watching from the glass window, fists clenched) He can barely speak and you want him to focus on lines.
Jeon Daewoon
(not turning) Yes. I don't want him to speak until he learns to speak with purpose. Every word should be calculated, precise. Just like every move.
Jungkook blinked up at his father.
He didn’t understand the harshness… but he obeyed.
His tiny hand reached for the blocks again.
Trembling.
The mansion was silent. Servants were dismissed and Guards were on high alert.
Mrs.Jeon tiptoed into jungkook's room nursery
Jeon Mira
( whispered) Shh.. My love. Mama's here now.
She scooped the sleeping child into her arms and held him close.
Her tears fell into his hair, but she didn’t let herself sob.
She couldn’t wake him.
Jeon Mira
( rocking slowly) You're not a weapon. You're not a monster. You're just... My little boy. And I'll protect what's left of your heart.
She hummed a soft lullaby, one her mother once sang to her.
Jeon Mira
(firm whisper) Daewoon doesn’t own your soul, Jungkook.
I’ll make sure he never does.
But outside the door… in the shadows… Daewoon stood.
Listening. Watching.
Jeon Daewoon
( dark murmur) So stubborn, Mira.
You’re only making it harder for yourself.
He turned and walked away, leaving cold footprints behind
Jungkook was four years old now.
He had never seen a playground, never played with another child, and never felt sunlight on his face.
His world was made of stone walls, locked doors, and cold hands that shaped him into a weapon.
In training hall at the morning
Jeon Daewoon
(firmly) pick up the dagger, Jungkook. let me see your stance.
Jeon jungkook
(quietly) okay Appa. I'll do it
Jeon Daewoon
(nodding) Good. Now, tell me where you strike if you want to injure but not kill.
Jeon jungkook
(focused) The shoulder.. or the leg.. Maybe the wrist.
Jeon Daewoon
and what if there's no room for mercy?
Jeon jungkook
Then I aim for the neck or the heart.
One of the guards stepped forward, kneeling with a soft smile.
He didn’t want to frighten the boy.
Bodyguard 1
Don’t worry, young master. We’re just practicing. I’ll go easy on you.
Jeon Daewoon
(sharply) He doesn’t need you to go easy on him. Treat him like a real opponent.
The training began.
Jungkook’s movements were fast and exact—far too advanced for a child.
The guard tried to dodge, but tripped and crashed into a metal hook on the wall.
Blood spilled to the floor.
Jeon jungkook
(panicked)I—I didn’t mean to hurt him! I didn’t want to—
hearing the panicked voice of her child, Mira rushed inside and saw jungkook looking at the bodyguard lying on ground with the blood dripping from his head.. probably dead now.
Jeon Mira
(anxiously) Jungkook! What happened? Oh no, he’s bleeding! What did you do?
Jeon jungkook
( tears welled up in his eyes) Mama, I hurt him. I was just doing what Appa told me. I didn't mean to..
Jeon Daewoon
( calmly) He did what he was taught. He followed orders.
Jeon Mira
(angrily) He’s a child! Not a soldier. Can’t you see how scared he is?
Jeon Daewoon
( kneeled infront of jungkook) You did well, son. The man was older, stronger, and yet you overpowered him. That’s something to be proud of.
Jeon jungkook
( confused) but.. he's hurt.
Jeon Daewoon
( firmly) That’s the price of survival. Never feel sorry for being strong. Never regret winning.
Jeon Mira
( tears welled up in her eyes) Strength isn’t about hurting people. He needs to understand that. He needs love too!
Jeon Daewoon
( coldly) love will get him killed.
saying that Daewoon pushed Mira outside the room and ordered his bodyguard to clean the room. Jungkook was still frightened and shocked and was looking at the floor.
Later that night, Mira sat beside Jungkook in his nursery.
He lay quietly under the covers, staring at the ceiling.
Jeon Mira
( gently) Sweetheart, can we talk?
I know today was hard. But it’s okay to feel scared sometimes. You’re not weak for feeling things.
Jeon jungkook
(softly) Appa says feelings are bad. He says people who cry are weak.
Jeon Mira
That’s not true. Being able to feel means your heart is alive. It means you care.
Jeon jungkook
(said quietly) But… you cry a lot. Appa never cries.
Jeon Mira
(shocked) I cry because I care about you, Jungkook. Because I’m your mother.
Jeon jungkook
(pulls away slightly) I don't want to be like you.. I want to be strong like Appa.
Mira’s heart broke hearing those words.
They weren’t her son’s words.
They were Daewoon’s.
Jeon Mira
(voice shaking) Even if you turn away from me… even if you stop calling me Mama…
I will never stop loving you. You’re my son. Always.
Jungkook didn’t respond.
He closed his eyes and turned away.
And for the first time… Mira felt like she had lost him.
World Apart
Jungkook was now ten.
Tall for his age, sharp-eyed, and impossibly calm for a child.
There were no scraped knees, no messy school notebooks, no childhood laughter echoing through the mansion.
Only the sound of footsteps, gunshots from the underground training room, and his tutor’s voice coming from a screen.
The sound of hard footsteps echoed through the mansion as Daewoon made his way toward the underground training hall. His eyes were sharp, cold, and unreadable—like always. Inside, Jungkook stood silently, holding a wooden practice sword. His posture was perfect, feet grounded, arms raised exactly how he was taught.
Daewoon stopper just a few feet away, folding the arms.
Jeon Daewoon
Han (said sharply, locking eyes with his bodyguard Han)
Jeon Daewoon
Don't you dare hold back today. He's not some fragile child who needs protecting. Treat him like a threat. If you go easy on him, you'll answer to me.
Han eyes hesitated for just a second, his eyes flicking toward the 10 year old.
Han ( Bodyguard)
yes Sir ( replied quickly, adjusting his stance)
Jeon Daewoon
(while looking at han) one mistake and I'll replace you with someone who knows how to follow an order.
Jungkook didn’t flinch. His hands gripped the sword tighter, and he looked straight at the man in front of him.
Jeon jungkook
I'm Ready (replied calmly)
Jeon jungkook
He won't go easy and neither will I. ( voice form but controlled)
The moment Daewoon gave the nod, the bodyguard lunged forward. Jungkook dodged, fast and smooth, and swung the sword low and sharp, hitting Han's shin before stepping back in perfect form. His breaths were steady, his expression completely blank.
Daewoon watched silently. He didn’t praise him, but the smallest shift of approval flickered in his eyes.
Jeon Daewoon
That's more like it. You're learning ( muttered under his breath)
After the session, Jungkook’s knuckles were red and bruised, but he didn’t complain. He simply stood there, waiting for Daewoon’s next words.
Jeon Daewoon
You lasted longer than yesterday. That’s progress. But progress isn't enough. You need to be untouchable. Learn to read their next move before they make it. (said coldly)
Jeon jungkook
I will. I want to be stronger (voice quiet but determined)
Jeon Daewoon
Good. Because the world out there doesn't care how old you are. If they see even a flicker of weakness in you, they'll tear you apart.
Later, back in the mansion, Mira waited at the edge of the hallway as Jungkook passed by. Her eyes softened the moment she saw him—bruised, silent, and alone.
Jeon Mira
Kook (she called gently)
Jeon Mira
wait please. Are you hurt?
Her hands moved to reach for his but he didn't stop walking.
Jeon jungkook
I'm fine ( replied without looking at her)
Jeon Mira
You don't have to say that (she said softly)
Jeon Mira
You don't have to act like nothing hurts. You’re still just--
Jeon jungkook
I said I'm fine. Father says pain is part of training. it's supposed to make me stronger.
Mira throat tightened hearing Jungkook
Jeon Mira
But you're a child (she whispered)
Jeon Mira
You're still just a little boy, Jungkook. You need love too. Not just orders and drills.
Jungkook finally turned to face her, his eyes colder than they had ever been.
Jeon jungkook
Love makes people weak. That's what Appa say. I don't want to be weak.
Jeon Mira
You're brave. You're smart but love isn't weakness,baby. It's what makes you human
Jeon jungkook
I don't need it( said firmly)
Her heart sank. She had lost him, bit by bit, year after year. He didn’t smile anymore. He didn’t call her Mama anymore. And now, he looked at her like she was just another person standing in his way.
When night fell, Daewoon stood in his office, reviewing Jungkook’s files. Every detail had been altered. To the world outside, there was no Jeon Jungkook. The documents listed him under a different name, enrolled in a private online institution, encrypted and hidden behind layers of forged records. No birth certificate, no school photos, nothing traceable.
Daewoon stared at the monitor, watching the silent feed of Jungkook’s room. The boy was seated at his desk, typing out an assignment with sharp focus. Not a single glance at his phone, no distractions. Just the faint sound of keys clicking.
A knock at the door pulled him from the screen. It was Han Jisoo, Daewoon’s most trusted guard—the only one allowed to be near Jungkook without explicit permission.
Han ( Bodyguard)
He's completing his lesson of the Day
Jeon Daewoon
He better be. I didn't raise him to waste time
Han hesitated before speaking again
Han ( Bodyguard)
He hasn't stayed with his mother all day. Should I-?
daewoon cut him off immediately
Jeon Daewoon
No. She's soft. Letting her near him now will undo everything I've worked for. Stay by his side. He doesn't need Mira. He needs discipline.
Han left from there and went to jungkook. In his room, Jungkook paused his work and looked at the closed window. His reflection stared back at him—expressionless, composed, too calm for someone his age.
he said suddenly without turning around
Han ( Bodyguard)
Yes, young Master
Jeon jungkook
Do you think I'll ever need friends?
There was a long pause. Han’s voice was low when he finally answered.
Han ( Bodyguard)
I think you'll need someone you can trust. Even if it's just one person.
Jungkook nodded slightly, but didn’t say anything else. His hands returned to the keyboard, typing line after line.
He was ten. But already, his heart had learned how to stay silent.
Jeon jungkook
Trust is dangerous. But maybe you're right ( muttered under his breath )
Somewhere far from the cold halls of Jeon Mansion, laughter echoed through a sunlit garden.
This was a world painted in color—warmth, love, and life.
Kim Taehyung
Catch me if you can, Minjae! you're too slow! (said while running, smiling widely)
Park Minjae (Taehyung's friend)
You cheated! You started running before I said go!
Kim Taehyung
There are no rules in fun. That's the rule! ( said while grinning widely)
Twelve-year-old Kim Taehyung was joy in human form.
Messy hair, loud laughter, and a heart too big for his chest.
Mrs. Kim called Tae from the porch
Kim Yujin (Taehyung's Mother)
Tae! Come have your juice before it gets warm!
Kim Taehyung
Wait for me, Minjae. I'll be back in a second!
Park Minjae (Taehyung's friend)
Don't take forever like last time!
Kim Taehyung
Mom, you should have seen how fast I ran today. I think I broke my own record
Kim Yujin (Taehyung's Mother)
You're always breaking records, Sweetheart.
Now drink up before you meltin that sun. (said while smiling, brushing his hair back)
Kim Taehyung
Thanks mom. Where's dad?
Kim Yujin (Taehyung's Mother)
He's still in the study. Probably still on the calls. You know how business keeps him busy.
Kim Taehyung
He promised to take me to the arcade this weekend! He better not forget
Kim Minho ( Taehyung's father)
And when have I ever broken a promise to my favourite son? ( said while walking toward them)
Kim Taehyung
Never! you're the coolest dad ever! ( Said while grinning widely)
The Kim household was filled with love, laughter, and stability.
Taehyung didn’t know darkness, secrets, or pain.
His world was sunshine.
His heart—unscarred.
Kim Yujin (Taehyung's Mother)
You've got music class at four. Don't forget.
Kim Taehyung
can Minjae come with me?
Kim Yujin (Taehyung's Mother)
Only if he promises not to distract you again
Park Minjae (Taehyung's friend)
hey! I'm a great musical influence! ( shouted while playing in garden)
While some children were shaped by blades and silence…
Taehyung was growing up surrounded by music, love, and endless chatter.
