The first time her son's fiancée, Xu Man, visits, she privately asks whether the mother's five-year-old daughter is actually the child of her older brother, Chen Che. At the engagement banquet, Xu Man brazenly demands a paternity test between the siblings in front of both families. The mother immediately sees through her malicious intentions and retaliates by demanding that everyone undergo testing. Unwilling to give up, Xu Man secretly cuts off the little girl's hair and submits it for testing behind the family's back. She then announces the results at a birthday party, only to discover that the mother calmly reveals her daughter's true identity. Later, when Xu Man spreads rumors, fakes a pregnancy, and teams up with Chen Yuan's uncle to cause trouble at the family's home, the mother exposes every lie. Chen Che finally sees Xu Man for who she really is and decisively breaks up with her. Through her actions, the mother proves one thing: whoever dares to touch my daughter will be the one forced out.
