Xu Changan worked hard at the construction site for fifteen years and worked hard to raise his daughter Xu Nianzhen. His wife Jiang Yun has been lying secretly about being busy with work all year round, but in fact she has been secretly communicating with her first love Qian Baiyu. After Xu Nianzhen won the first place in the county, he directly exposed the lie that his mother was busy with work at the award ceremony, which instantly sparked a heated discussion. Neighbor Lao Ma bumped into Jiang Yun and Qian Boyu being intimate at a parent-teacher meeting. Conclusive evidence was put in front of them, and Jiang Yun collapsed and confessed. Xu Changan decisively filed for divorce and completely got rid of the bad marriage. The father and daughter lived a stable and warm life from then on.
