A ruthless mafia boss hiding in plain sight. An undercover cop consumed by a feral obsession. Dunk thought he was hiring a bodyguard. A human shield to protect him from the crossfire of the underground. He didn't know he was inviting his worst enemy and the greatest predator right into his bedroom. Joong thought he was playing a role. A calculated seduction to dismantle a criminal empire from the inside out. He didn't know he was about to risk his career, his freedom, and his life for the very man he was supposed to put in chains. In a world where one wrong move means death, falling in love is the most dangerous crime of all.

A rising boxer who lives by discipline, control, and winning... never expected to lose his heart. When he crosses paths with someone completely outside his world, what starts as tension slowly turns into something neither of them can stop. But love isn't the only thing growing between them and secrets don't stay hidden forever. What he doesn't know? His own brother has been watching... wanting... and waiting. As jealousy builds and betrayal cuts deeper than any punch, family turns into enemies, trust shatters, and love becomes the biggest risk of all. And when everything finally comes crashing down he realizes some fights aren't won in the ring. Especially when the person he loves is now carrying a future neither of them planned.
