Bloodstained Vows & Sinful Desires

Before he became the untouchable king of the underworld, Kim Taehyung was just a man—a son, a lover, a prince destined for greatness. But power doesn't come without sacrifice, and in his world, love is the deadliest weakness of all.

He trusted her—the woman who once whispered promises against his skin, the only soul he ever let past his walls. He built an empire for her, bled for her, and worshiped her. But love? Love was his greatest mistake. She betrayed him. And with that single act, she didn't just break his heart—she shattered the man he once was.

The night he lost everything, the devil was born.

Now, Kim Taehyung is no longer the heir. He is the executioner. Ruthless. Merciless. Unforgiving. With blood on his hands and vengeance in his heart, he carved his name into the underworld, burning every trace of the man he used to be. He doesn't crave love anymore—he craves power, control, and the sweet satisfaction of destruction.

But ghosts of the past never truly die. And when she returns—begging, bleeding, hiding secrets behind those lying eyes—he's faced with a choice: bury her in the grave she dug for herself or let her ruin him all over again.

Because in his world, betrayal is a death sentence. And forgiveness? That's a mercy Kim Taehyung no longer believes in.
