From Ex to Sister-in-Law

On her wedding day, the once-excited bride Qin Siyao accidentally catches her fiancé, Mu Tianfan, in bed with her sister. Devastated by the betrayal, Qin Siyao tries to confront them, only to be physically harmed by the pair. They cruelly reveal another unbearable truth: Qin Siyao is no longer the heiress of the Qin family. Meanwhile, Mu Tianchu, who has just returned to the country to attend his younger brother’s wedding, is busy dealing with his family’s hostility toward Gu Keke. By chance, he witnesses Mu Tianfan and Qin Kewei abusing Qin Siyao. Out of sympathy, Mu Tianchu steps in to rescue her. Mu Tianchu offers Qin Siyao a deal: he will help her take revenge, but in return, she must become his wife. Just when Qin Siyao had lost all hope for justice, Mu Tianchu’s proposal rekindled her fighting spirit. She agrees and signs a contract with him.
