The Ereño family once owed everything to the Perez empire-until a series of failed deals and hidden debts drove them to ruin. To save her parents, Daniella Ereño was forced to sign a contract with Dave Perez, heir of the Perez dynasty and one of the rumored masterminds behind the secret "Chess Piece Organization." Her role was simple yet cruel-be his bed slave until he no longer wanted her. No love. No mercy. Just obedience. But Daniella despised him-the arrogance in his voice, the power in his hands, the way he looked at her like she was a pawn in his game. Until she discovered something darker: Dave wasn't just a cold-hearted man. He was also the new Challenger, a player in a deadly underground game where each move meant life or death-and where the pieces weren't just symbols, they were people. As the game reopens, both of them are trapped on opposite sides of the board. Dave fights to protect the woman he swore to use. Daniella fights to survive the man who owns her. But in a world ruled by strategy, betrayal, and power, can love survive when every move could destroy them both? And when the final round comes... will he sacrifice her to win, or break the rules to save her?
