The debt is unpaid, and the price is Jeon Jungkook. Taken by Kim Taehyung - the ruthless mafia king who rules his empire with blood and silence - Jungkook is forced into a marriage that was never his choice. His loyalty belongs to no one but himself, yet every step he takes inside Taehyung's world pulls him deeper into a brutal game of control and survival. Taehyung is dangerous, magnetic, and utterly unreadable - a man who demands obedience but hungers for more than submission. To him, Jungkook is both prize and threat, a defiance he cannot crush and a flame he cannot resist. Between them lies a bond forged from chains: toxic, consuming, and impossible to escape. In a world of debts and crowns, one truth remains; what begins as captivity may end in devotion.
