Xu Changan worked hard at the construction site for fifteen years and took full responsibility for his family and daughter. However, his wife Jiang Yun used work as an excuse to stay with his first love and absent from the family for a long time. After finding out, her daughter Xu Nianzhen secretly investigated for three months and exposed her mother's lies in public on the podium with the first place in the county, causing a public uproar. Xu Changan also learned from his neighbor about Jiang Yun's affair with his first love Qian Boyu. In the face of irrefutable evidence, Jiang Yun admitted her mistake, and Xu Changan resolutely divorced. With her daughter's evidence, she won the case and obtained custody and real estate. Qian Baiyu was fired and prosecuted for embezzlement of public funds, and the father and daughter finally ushered in a new life of peace and warmth.
