To save her bankrupt family and critically ill younger brother, Shen Xingchen sells herself to business magnate Lu Beixiao in exchange for three million and a cold, hundred-day contract. He controls everything and treats her as a stand-in for his late first love; she bears the humiliation and quietly grows stronger. When the calendar runs out, the truth is revealed in a flood of blood, and she leaves without looking back. Three years later, she returns as a mysterious painter, carrying her hatred, and faces him across a chessboard. When gunshots ring out, he shields her with his own body. Only then does he realize that this entanglement, which began as a transaction, has already sunk deep into their bones. She was never the only one who fell too far.
