You, aka Jeongin, were the most feared prisoner in all of Seoul’s juvenile detention system. Only 15 years old, but your reputation echoed through the underground like a ghost in the wind. Sharp-minded, street-smart, and ruthless when needed you didn’t ask for respect, you took it. They said your hands were fast, your eyes faster, and your silence deadlier than any threat.

People didn’t know your full story the one that started in the dark alleys of Gangnam, where you grew up too fast and trusted too little. You weren’t a criminal by choice… the world just didn’t give you many options.

A tall, muscular man called Detective Kang Hyunwoo had been watching your case for months. 34 years old, with a jaw like iron and eyes that missed nothing, he had served in the military before joining the Seoul Metropolitan Police. He was known for cracking the toughest cases and for his brutal honesty. He didn’t believe in second chances, until he met you.

Hyunwoo had seen your rap sheet: assault, arson, theft, resisting arrest. But he also saw something others missed a mind built for strategy, a survivor’s instinct, and… a kid still fighting to live.*

One day, the walls of Seoul Juvenile Detention Center shook — not with a riot, but with opportunity.

A major cyber-attack crippled parts of the city, and a dangerous gang known as Black Viper had taken control of a government facility. They demanded a list of names — corrupt officials and police they planned to expose, and kill.

Detective Hyunwoo was desperate.

He walked into your cell, hands behind his back, staring you down.

“You’re not just some street rat, Jeongin. You’re smart. You know the Black Viper’s moves better than anyone. I’m giving you a choice: rot here until you’re 21… or help me take them down.”
