The boy who walked into the lion's den
The city at night was never silent. Sirens, distant engines, and the metallic heartbeat of danger echoed through every alley. But nothing compared to the atmosphere inside Jeon Jungkook ’s mansion—the home of the most feared mafia king at just twenty-five.
The marble floors gleamed like ice, the air cold and sharp, and every shadow hummed with the presence of trained killers.
But that night… something different entered those halls.
Something soft.
Something small.
Something that had no place in the world of blood and guns
Taehyung.
Only nineteen, backpack hanging off one shoulder, wide eyes taking in the mansion like he’d been dropped into the wrong video game.
He had been brought by accident—he witnessed something he shouldn’t have. The guards expected him to scream, faint, or beg.
But tae only whispered:
tae
Umm… is there… a bathroom? I really need to pee.”
The entire mafia froze.
Someone dropped their gun.
Someone else coughed to hide a laugh.
No one talked like that in front of Jungkook.
And definitely not in front of Jungkook, who now stepped into the hall.
Tall, broad-shouldered, dressed in black, eyes sharp enough to cut a throat. He walked like a man born to be obeyed. Every step echoed authority.
Tae… didn’t even notice him at first.
He was too busy staring at the giant chandelier.
jk
Jungkook stopped three feet away.
jk
"Look at me,” he ordered.
His voice was deep—dangerous—but smooth enough to make your spine react before your brain did.
tae
tae slowly turned.
Their eyes met.
jk
Jungkook expected fear.
tae
Instead… tae blinked innocently.
tae
"Oh. You’re… the boss guy?”
The room nearly exploded internally.
The boss guy
No one had ever called jungkook that and survived.
But jungkook … didn’t get angry.
He stepped closer instead. Too close. Close enough that tae had to tilt his head back to meet his eyes.
jk
“Who are you?” jungkook asked quietly.
tae
“T-Taehyung,” he said, clutching his bag. “I—I sell handmade keychains outside the station. I didn’t mean to—uh—come here. Your men just grabbed me like I’m a potato sack.”
tae’s honesty was so raw, it stunned the king.
tae
tae’s messy hair, soft eyes, tiny frown, trembling hands—but not trembling out of fear.
tae
Trembling because he was overwhelmed.
jk
jungkook lowered his voice.
jk
“Did you see anything you shouldn’t have?”
tae
tae shook his head fast.
tae
“I don’t even look at spilled ketchup properly. I swear I didn’t see anything.”
jk
jungkook ’s lips twitched.
Not a smile.
Something more dangerous.
Amusement.
Interest.
Possession is beginning to bloom.
jk
Then he turned to his men.
The hall emptied instantly.
tae
tae swallowed. “D-Did I do something wrong?”
jk
jungkook another step forward. tae backed up until his spine hit a pillar.
jk
jungkook placed one hand beside tae’s head, caging him in.
jk
“You came into my world, taehyung ”
jk
“So now,” jungkook interrupted, leaning closer, “you’ll stay under my watch.”
tae
tae froze, heart pounding so loud it echoed.
tae
"Stay… here?” he whispered.
jk
"Yes,” jungkook murmured. “In this mansion. With me.”
tae
tae stared up at him, dazed.
jk
jungkook brushed a finger lightly under tae’s chin. tae’s breath hitched—small, soft, helpless.
jk
“Because I don’t let good things… slip away.”
tae
tae’s cheeks turned hot pink
jk
jungkook straightened, expression unreadable but eyes burning.
tae
tae followed like a confused puppy.

Don't forget to support me
first claim
The moment jungkook walked away with tae, his closest men emerged from the shadows.
suga
Smirked. “The king is interested. We’re doomed.”
jimin
Leaned on his gun. “That boy is sunshine. jungkook is… a thunderstorm.”
namjoon
Exhaled. “This combination is going to destroy us.”
jin
Clasped his hands. “He’s cute😍… I want to protect him.”
kai
Grinned. “I like him already.”
j hope
Laughed softly. “Can’t wait to watch jungkook struggle with basic emotions.”
jungkook personally guided Ethan to a room.
A king.
Guiding a stranger.
Everyone was speechless.
jungkook opened the door.
A simple guest room—soft bed, warm light.
tae
taehyung stepped in slowly.
jk
jungkook watched him carefully.
jk
“You’ll stay here. No one enters without my permission.”
jk
jungkook stepped forward again, lowering his head so their faces were inches apart.
jk
“Because from this moment,” he murmured, “you’re under me.”
tae
tae nearly choked on air.
tae
“I—I think you mean under your protection?”
jk
“Mm. If that makes you comfortable.”
tae
tae’s face turned red. ( like 🍅🍅)
jk
jungkook’s tone softened—just barely:
jk
“I won’t harm you. You’ve done nothing wrong.”
tae
tae’s shoulders relaxed with relief
jk
jungkook wasn’t expecting the next line:
tae
“You’re… nicer than you look.”
jk
No one had ever used that word for him.
He stared at tae longer than he should have.
Then he spoke quietly:
“Don’t trust people so easily… tae.”
tae
“Even you?” tae asked softly.
jk
jungkook’s throat tightened.
“No,” he whispered. “Especially me.”
tae
But tae only smiled gently.
tae
“I don’t think you’re a bad person.”
jk
jungkook inhaled sharply.
That soft, sincere voice…
It hit him somewhere he didn’t know existed.
He turned away suddenly.
“If you need anything… call me.”
tae
tae blinked. “Call you? Like on the phone?”
jk
jungkook stopped at the door.
jk
“I’ll hear you,” he said.
His voice is deep.
Possessive.
Final.
jk
jungkook didn’t look back—but his hand tightened on the doorframe.
He was already falling.
Hard.
