Zhang Wei and Guan Gu are sitting in a bar chatting. Because it is Christmas, Zhang Wei chatted with Guan Gu about the story of Santa Claus. While they were talking, Tang Youyou and others came along. When Zhang Wei talked about Santa Claus, Hu Yifei thought of the Christmas tree that Ceng Xiaoxian moved back, so he and Zhang Wei talked about the Christmas tree that appeared in the apartment building.

Tang Youyou and Guan Gu talk about premarital examination. In order to make Guangu realize the importance of premarital check-up, Tang Youyou revealed that there was a newly married couple upstairs who had been married for two years. The woman found that the man had a potential mental illness, and every day the man imagined himself as a toilet.

Guangu was a little unhappy after hearing Tang Youyou's words, thinking that Tang Youyou was worried about his potential mental illness. When Tang Youyou saw Guan Gu's misunderstanding, he quickly explained why he wanted to have a premarital examination, mainly because he wanted to know more about Guan Gu.

In the bar, Lv Ziqiao chats with Tang Youyou and Guangu. During the chat, Lv Ziqiao revealed that she knew a girl. Out of curiosity, Tang Youyou asked Lv Ziqiao about the girl's name and learned that Lv Ziqiao didn't know the girl's name. Tang Youyou was in distress situation about Lv Ziqiao's way of making friends. Lv Ziqiao looked at Tang Youyou seriously and revealed that she wanted to ask the girl's name. As a result, the girl refused to say her name.

An unknown woman and Lv Ziqiao are eating in a restaurant. At dinner, a strange woman asked Lv Ziqiao some questions. Lv Ziqiao looked at the strange woman seriously, claiming that if she answered the question, there would be no mystery.

The strange woman saw that Lv Ziqiao didn't want to answer questions, so she got up and went to the toilet to chat. Lv Ziqiao called Tang Youyou while the woman was going to the toilet, hoping to find out the identity information of the strange woman.

Tang Youyou helped Lv Ziqiao find information about the unknown woman, and Lv Ziqiao returned home to repay Tang Youyou with a massage.

Later, Tang Youyou found another screen name for the girl. Through this screen name, she found the girl's diary, that is, the death note.

Hope to adopt! ! ! ! ! !
