Su Wan realized that her husband Chen Lei had betrayed her, so she hurried home, only to be blocked from the bedroom door by her mother-in-law Chen Guilan. She summoned her parents and brothers and started a fierce confrontation with her mother-in-law and Chen Hong. Xiaoya showed up unexpectedly to dispel some of the doubts, but Su Wan insisted on unlocking the door. The locksmith was driven away by Chen Hong on the grounds that he was "not the head of the household." Su Wan was angry and used an ax to open the door, only to find that the room was empty. Everyone thought there was a misunderstanding, but Su Wan discovered that the door to her mother-in-law's room was locked. After opening it again, Chen Lei's affair with his best friend Bai Ling was completely exposed. Su Wan decided to divorce and kicked everyone out of the house.
