Hongjing No. 8 Middle School won consecutive games against Lvjing International and Yuzhou Silver Elephants, becoming the most promising team in the city. In order to celebrate the win, Yu Bo prepared Internet celebrity fried skewers to celebrate for everyone. Wang Fa was about to invite Lin Wanxing to relax together, but Lin Wanxing looked indifferent, saying that he had a toothache, and turned around to leave.When he got home, Ju Li was waiting at the door and prepared dinner for Lin Wanxing. Seeing that Lin Wanxing was unhappy, he didn't want to say too much, so he left the dinner for Lin Wanxing to eat by himself.After a while, someone knocked on the door, and it was Wang Fa who opened the door. Wang Fa asked why he had been blocked on WeChat. Lin Wanxing explained that he already knew that Xiao Ming was Jason. Wang Fa knew that Lin Wanxing could not forgive him for a while, so he showed Lin Wanxing the clues he had compiled.

Lin Wanxing looked at Wang Fa's records alone, and called Wang Fa into the room to explain what he knew. He and Jason met on a forum. Jason's parents divorced when he was young, so he longed for his father's love. He always pushed himself to be better in order to win his father's favor. Lin Wanxing once sent Jason a box of biscuits, which was swapped by the Queen of Spades for illegal drugs. Later, Jason once said that he hated Lin Wanxing. Lin Wanxing didn't understand it at the time, but now he knows the reason.Wang Fa remembered that Jason had sent him a photo of a butterfly before the accident, and immediately showed it to Lin Wanxing. Lin Wanxing discovered that it was his senior brother Xiang Zi's favorite photo. The two had gone to the UK as exchange students together, and Lin Wanxing had rejected Xiang Zi's confession. Now that he had an unshirkable responsibility, Lin Wanxing requested to investigate with Wang Fa.

Lin Wanxing and Wang Fa visited Xiang Zi's home. Xiang Zi seemed very familiar with Lin Wanxing. Wang Fa explained that he wanted psychological counseling. Regarding his student's suicide, Lin Wanxing introduced his relationship with Wang Fa. The two were colleagues and tenants, so it was not convenient for acquaintances to consult. Xiang Zi said that it was not convenient at the moment and he could make an appointment in advance.Seeing that Xiang Zi was a little angry, Lin Wanxing went downstairs and deliberately asked Wang Fa to open the car door for him and help him fasten his seat belt, showing that they were a couple. As expected, Xiang Zi secretly watched from the window, and the more he watched, the more angry he became.
