Rain fell heavily over Seoul.
The city lights reflected across the wet streets like broken diamonds.
At the top floor of a luxurious skyscraper overlooking the Han River stood a man who controlled nearly half of South Korea's underground economy.
His name was Kang Tae-hyun.
Most people called him Kang Tang.
At thirty-two years old, he had achieved what many considered impossible.
Money.
Power.
Fear.
Respect.
Every criminal organization in Seoul knew his name.
Every politician feared his influence.
Every businessman wanted his protection.
Yet none of those things mattered tonight.
Because he had been betrayed.
Kang Tang slowly looked around the conference room.
Three men stood before him.
Men he once trusted with his life.
Lee Do-jin.
Han Ji-hoon.
Park Sung-min.
His closest friends.
His brothers.
The people who helped him build the Black Dragon Mafia from nothing.
Now each pointed a gun directly at him.
The irony almost made him laugh.
"You look surprised," Lee Do-jin said.
Kang Tang stared silently.
Surprised?
No.
Disappointed.
Very disappointed.
"I trusted you."
His calm voice echoed through the room.
Han Ji-hoon smirked.
"That's why you lost."
Rain crashed against the giant glass windows.
For several seconds nobody moved.
Finally Kang Tang sighed.
"How much?"
The three men exchanged glances.
"What?"
"How much money did they offer you?"
Lee Do-jin laughed.
"You still don't understand."
Kang Tang narrowed his eyes.
"It was never about money."
The answer shocked him.
Not money?
Then why?
For ten years they had fought together.
Suffered together.
Built everything together.
So why betray him?
Lee Do-jin stepped forward.
"Because nobody wanted to live under your shadow forever."
The words hit harder than any bullet.
Jealousy.
Simple jealousy.
