During Xu Zhixia's wedding tea ceremony, her biological parents, who had been separated from her for thirty years, barge in with her younger siblings and kneel to claim her as their daughter. A paternity test confirms their blood relationship, but Xu Zhixia soon realizes that the Song family has not come to find her and atone for the past; having heard of her success as an entrepreneur, they have come to demand a share of her wealth. Her younger brother, Song Chao, is lazy and greedy, constantly demanding property and a job, while her parents use the moral obligation of giving birth to her to manipulate her. Her eldest sister, Song Chunyan, secretly reveals the truth: Xu Zhixia was not lost all those years ago but was given away by the Song family simply because she was a girl. Remembering the kindness of her adoptive parents, Xu Zhixia confronts the greed and favoritism of her birth family, tears apart their false pretense of family affection, decisively cuts ties with them, and protects her happiness and boundaries.
