On Father's Day, Wang Zhi discovers that of his twins, his daughter is his biological child, while the son he has raised for five years is actually the child of his wife's first love, Gu Minglang. Their five-year marriage has been built on lies since their wedding night. His wife has long favored the boy and mistreated their daughter, and the truth leaves Wang Zhi utterly disillusioned. He decisively files for divorce, gathers evidence, and strikes back step by step, exposing Gu Minglang's true nature: faking a disability, cheating during the marriage, and committing business crimes. He makes the betrayers pay for what they have done. In the end, Wang Zhi starts a new life with his biological daughter, while Bai Wan and Gu Minglang are disgraced and meet a miserable fate. A fast-paced story of marital betrayal, the truth about parentage, and the satisfaction of revenge, packed with emotional tension and cutting to the heart of family and human nature.
