Jeonghan, an ordinary university student, who finds himself ensnared in the world of Seungcheol, a ruthless mafia leader with a dangerous obsession. As Seungcheol's affection becomes a suffocating force, Jeonghan's life spirals into chaos, where freedom is an illusion and every move is monitored. Trapped in a mansion of luxury and terror, Jeonghan must confront the twisted love Seungcheol offers, grappling with the constant pull between submission and rebellion. Seungcheol: I'll make you mine, Jeonghan. No one can take you from me. Not now, not ever. Jeonghan: You think you own me, but I won't be controlled. I'll fight-no matter what you do to me. Seungcheol: You already belong to me, whether you admit it or not. There's no escaping what's already yours. Jeonghan: I'm suffocating in this cage of your making, but maybe... maybe I've already lost the will to fight.

The Choi family and the Hong family have been the two leading families of the mafia world. They've built their legacies from nothing, and will do everything in their power to keep them. Seungcheol Choi has always been taught two things, always fight for yourself and never trust a Hong. He never planned to, growing to hate the Chois just as much as his family did. But when they two families are forced together, the hatred he always felt for the Hong's becomes much more complicated. Jeonghan has always known about his family's business in the crime world, but he has never wanted to be apart of it, at least not like his older brother Joshua did. But when a fatal accident leaves one of Joshua's family members dead , he is left with no choice but to join the business he's been so desperately running from.

When Seungcheol walks out of his wedding minutes before the vows, he never expects to end the day married to his ex-fiancée's brother. But Jeonghan isn't running from love-he's running from control. One impulsive marriage that turns into the sweetest disaster of their lives. Love wasn't in the plan-but neither was happiness this real.
