DARK LEOPARD
Life behind iron bars is reserved exclusively for the strong and the ruthless. When Li Do Hwan stepped into this concrete purgatory as an ordinary inmate, he had only one objective: survive in silence. But in this living hell, silence is a death warrant—especially under the reign of "Dragon," the prison's underground king and the head of a terrifying mafia syndicate whose very name makes the most hardened criminals tremble.
To secure his safety, Do Hwan tries to claw his way into Dragon’s inner circle. Instead, his dangerous investigation uncovers a shadow network whose reach extends far beyond the prison walls. His search leads him directly to Jang Si Woo, the quietest and most enigmatic ghost in the facility. But Si Woo is hiding a lethal truth: he is Dragon’s adopted son and the sole heir to the entire criminal empire.
In a place where any guard or inmate could be a planted assassin, a single misstep carries a fatal price. After his only true confidant, Kim Do, is brutally ambushed and left for dead, Do Hwan realizes that the time for enduring in silence is officially over.
The weak Li Do Hwan is dead. In his veins flows pure, calculated rage. Caught between broken bones, blood-stained tiles, and a hand of friendship extended by the prince of the underworld, he makes an unyielding vow: to bring Dragon to his knees and systematically erase his empire from the roots.
From the deepest shadows of the abyss, a new apex predator is awakening... The Black Leopard.
"If all the pain piling up inside my heart must explode one day with a terrifying scream, that explosion will turn your entire empire to ash, Dragon."
