Killian is a 21-year-old cartel enforcer known for his brutal efficiency, emotional detachment, and reputation for being more weapon than man. Life for him is control, silence, and violence—until he meets Y/N, an ordinary girl who unknowingly disrupts everything he understands about himself. Drawn to her in ways he cannot explain or control, Killian’s fixation quickly turns into something dangerously obsessive, blurring the line between protection and possession. As rival forces close in and his world begins to destabilize, Y/N becomes both his greatest weakness and the only thing that makes him feel human, forcing him to confront whether love can exist in a life built on blood—or whether it will destroy them both.
