"Loyalty can be bought. But love? That's dangerous."
Soobin was born into power-heir to a dangerous criminal empire, trained to rule with silence, fear, and a gun always within reach. But everything changes the night he crosses paths with Yeonjun, a bold, sharp-tongued bartender who accidentally becomes entangled in the underworld's darkest secrets.
What starts as a mistake becomes an obsession. Soobin takes Yeonjun under his protection, into his world of brutal politics, family betrayal, and blood-soaked loyalty. But Yeonjun doesn't belong in a cage-he's fire, and he refuses to burn quietly.
As enemies close in and secrets unravel, Soobin is forced to make an impossible choice: uphold the rules he was raised to obey, or break every one of them to protect the only person who ever made him feel alive.
This is a story about power, redemption, and the kind of love that doesn't ask for permission.
Because in Soobin's world, nothing is free-
Not even your heart.

"I honestly just wanted to be a life mentor!"
