It was midnight.
The city of Uyama lay in restless sleep, cloaked in a soft drizzle of rain and silence — until the sudden, deafening sound of a gunshot split through the night like a scream.
In the towering Uyama villa at the city's edge, that single shot shook more than just windows — it shattered lives.
Bang.
Sunghoon bolted upright in his bed, breath caught in his throat. His heart slammed against his ribs like it was trying to escape. The air felt heavy, electric, like the calm before a storm.
A second later, he was on his feet. The cold floor bit into his bare soles as he reached for the silver pistol under his pillow — an old habit. His fingers were already trembling.
That sound... it came from inside the house.
He didn't think. He ran.
Down the corridor, past the ancestral paintings, past the hall lit dimly by flickering wall sconces, like the house itself was holding its breath.
His parents were already awake. Mr. Kim, stern as ever, stood at the top of the stairs, his jaw clenched. Mrs. Kim, wrapped in a silk robe, looked pale, confused. Her hands trembled as she gripped the rail.
"The basement," Sunghoon said, voice low and cold.
"Yuna... she was sleeping downstairs tonight," his mother whispered.
No one needed to speak again.
Sunghoon led the way, each step faster than the last, his grip tightening around the pistol. He could hear his mother's breath quicken behind him, and his father's heavy, stiff footsteps.
When they reached the basement door, it was slightly ajar.
The air that seeped out was cold... too cold.
He pushed the door open fully — and time stopped.
The sight hit him like a blade through the heart.
Blood.
So much blood.
Yuna was lying there, in the center of the floor. Sixteen years old. The light of the Uyama family. His baby sister.
Her school hoodie was stained dark crimson, her hands limp by her sides. Her lips were pale. Her skin ghost-white.
Her eyes… were still open. Staring at nothing.
A faint light bulb above flickered, casting an eerie glow over her small body. She looked like she could still be breathing — like she might blink at any second. But she didn't.
Mrs. Kim let out a sound that didn't even sound human. A scream that shattered the silence like glass. She collapsed to her knees beside Yuna's body, sobbing, reaching out as if her touch could bring her back.
Mr. Kim stood frozen at the doorway, not a single word leaving his mouth. His face was blank, but his hands were shaking.
Sunghoon couldn't move.
His knees almost buckled, but he forced himself forward.
He knelt beside his sister, one hand hovering over her bloodstained hair. His breath was shallow. His throat burned.
"Yuna…" he whispered, but she didn't answer.
Her face still looked like an angel's. So young. So pure. So undeserving of this.
He touched her cheek. Cold.
She was gone.
He clenched his fists until his knuckles turned white. The rage crawled up his spine like fire. His vision blurred, not from tears — from fury.
Who did this? Who dared?
Sirens echoed in the distance. Someone had called the city guards. Word was already spreading. The villa grounds lit up with patrol lights and panicked voices.
But none of that mattered. Not yet.
A single piece of paper sat on the floor beside Yuna's hand. It looked like it had been placed there intentionally.
Sunghoon picked it up slowly. His jaw clenched as he read the words, printed in a neat but taunting script:
"How was the surprise, Sunghoon?
Minji is back.
Get ready to face more disasters."
Minji.
The name hit him like a slap to the face.
No. That wasn't possible. He had killed her.
A year ago, Minji — the eldest daughter of the Dragon Clan — had trespassed into Uyama territory and spilled innocent blood.
Sunghoon had dealt with her himself. He saw her bleed. He watched her fall.
There was no way she was still alive.
And yet… here was her message. Here was his sister, lifeless at his feet
A chill ran down his spine.
How is this possible ?
(Character Profile – Sunghoon Kim)
Full Name: Kim Sunghoon
Age: 24
Height: 200 cm (6'6")
Role: Male Lead / 5th Generation Mafia Heir
Parents: Mr. Kim & Mrs. Kim — current rulers of Uyama
Position: Sole heir to the Uyama Mafia Empire
(Personality:)
Cold and emotionally distant
Responsible and deeply calculating
Speaks less, observes more
Loyal to his family, haunted by his sister's death
Has a soft core buried under years of discipline and control
(Background:)
Born into the powerful Kim family, Sunghoon was raised with silence, strategy, and shadow. His life was built on discipline, duty, and preparing to inherit the empire hidden beneath Uyama's quiet streets.
His entire world collapsed when his younger sister Yuna was murdered — a tragedy that triggered a cold war between mafia clans. Since then, Sunghoon has been consumed by vengeance, determined to make the Dragon Clan pay.
(About Uyama:)
Uyama is a modern, elegant city on the surface — clean streets, high-end schools, peaceful neighborhoods. Tourists and residents see calm and order. But few know that the city thrives under mafia rule, kept balanced by an unspoken pact between rival families.
The Kims have ruled Uyama for five generations, maintaining peace through fear, control, and ruthless diplomacy. While other cities burn with crime and chaos, Uyama remains mysteriously untouched — because the real power doesn't wear a badge… it wears a family name.
Of course — here's a beautifully emotional and powerful character profile for Yuna, the victim and younger sister of Sunghoon, whose death ignites the entire plot of Stolen For Vengeance.

(Background & Role in the Story:)
Yuna was the heart of the Kim family. Unlike Sunghoon, she was protected from the dark side of their empire, allowed to grow up freely, away from blood and power. The family's golden light — cheerful, full of dreams, and innocent to the world's cruelty.
But her last moments were anything but kind.
At just 16, Yuna became the casualty of a brutal warning — killed in cold blood. No ransom. No chance.
Her body was left in the Uyama villa like a message carved in silence.
Her death shattered Sunghoon.
It broke the peace.
And it lit the match for a war no one can stop.
( Her Legacy)
She wasn't just the youngest heir of the Kim bloodline —
She was the reason Sunghoon still had a heart.
And now that she's gone…
He's making sure someone else pays the price.
