In a sudden turn of events, Wan De Fu and Tu Shu Li decided to end their 32-year marriage. Both soon realized they had made a mistake, but neither was willing to back down. They reluctantly began dividing their assets, including a detective agency that neither wanted to lose. In order to keep their agency running smoothly, they agreed to continue living in their 3-story apartment and operating their business on the first floor. However, their plans were disrupted when their daughter returned home with their granddaughter following a disagreement with their son-in-law. Additionally, new tenants, who had been rented to by Tu before the divorce, started moving in.
