Meiyun holds a knife to Junyan’s neck and cuts him. He screams in pain. Thinking she has heard Haowen’s voice calling out to her, however, she becomes distracted. Yuyang grabs the opportunity to subdue her. Meiyun hated Xiaoqing for causing her son, Haowen, to commit suicide. To avenge her son, she murdered Xiaoqing and set Haifeng up, using Jieming to create the impression that Haifeng was the murderer. Haifeng calls Meiyun a lunatic. She reveals he is soon going to be like her, as she has been adding poison to his food. He is stunned. Meiyun is sent to a psychiatric hospital. Jieming tends to her. Haifeng discloses that Meiyun has killed the wrong person, because Haowen liked Xu Qingqing, not Xiaoqing. Psychiatrist Zheng Pinghe informs Haifeng that his food contained a mild antidepressant, which is not harmful. Pinghe reminds his mother, Song Lizhu (Lina Ng), about their excursion the next day. She refuses to go, making the excuse that she is not feeling well. Lizhu is in her room alone. She mourns the loss of her husband, Zheng Caifa (Zhang Wen Xiang), and their three children, who were murdered 28 years ago. Pinghe watches her with a heavy heart. Qingxiong announces that Haifeng has joined CCI and has agreed to let them use his house as a CCI office. He also discloses that Pinghe has hired them to investigate a 28-year-old murder. Qingxiong goes to Pinghe’s house to learn more about the case. However, Lizhu becomes agitated and demands Pinghe halt the investigation. Qingxiong seeks out Caifa’s brother, Zheng Caishun (Wang Yuqing). He, too, hopes CCI will respect Lizhu’s wishes and end their investigations. The CCI team re-enacts the crime scene. Qingxiong and Yuyang deduce that the murderer was someone close to the victims. Junyan and Haifeng are baffled.
