Episode 4 recap: Class 11, which is not recruiting enough students, is about to be canceled.

Sang Xia was complaining to a friend about Lei Ming's bizarre behavior, as if he were a complete idiot in life. He even sends himself bargain messages from Pinduoduo every day. With the guidance of a friend, Sang Xia also decided to join Class 11 with Lei Ming. After all, most of the students in Class 11 have problems, so it can be considered as an experiment for their own psychological counseling.

If we go back three days, Lei Ming's father was very angry because of his return. Lei Ming said that he came back this time to be a good teacher and didn't necessarily seek his father's approval. He originally wanted to send his father to a sanatorium, but his father always disagreed.

Lei Ming walked alone on the street and entrusted a kitten to someone else because he had to take care of the students. Lei Ming also showed a shop to an aunt, but she didn't appreciate it and said that Lei Ming was not that kind of person at all. It seems that Lei Ming also has some hidden secrets.

Lei Ming suddenly saw a girl by the river, but she disappeared in the blink of an eye. Lei Ming felt relieved. Cheng Yu Shan is now very afraid of someone knocking on the door at night. Today, it was Cheng Yu Shan's mother who came knocking on the door and gave her money for school uniforms. Cheng Yu Shan didn't know what to say, so she took the money and quickly closed the door.

Sang Xia was chatting with Cheng Yu Shan on the rooftop and mentioned how she was once rumored by classmates when she was studying. If she hadn't met a good teacher, she wouldn't have become who she is now. Sang Xia also comforted Cheng Yu Shan, saying that she is currently weak, but one day Cheng Yu Shan will stand up too.

Sang Xia is not asking Cheng Yu Shan to join Class 11, but she hopes that Cheng Yu Shan can protect herself. Whenever Cheng Yu Shan needs help, Sang Xia will be there for her. After a long consideration, Cheng Yu Shan sent a message to Sang Xia saying that she is willing to join Class 11.

Xiao Xiao is a people-pleaser at school and brings a lot of delicious things to her classmates every day.

Lei Ming showed Sang Xia another student named Jiang Qing Lang. Although he is not good at academics, he has some fame in school for his rapping skills. Lei Ming took an interest in him and wanted to bring him into Class 11.

During an exam, Jiang Qing Lang kept cheating. Lei Ming deliberately distracted the teacher, allowing Jiang Qing Lang to use his phone to search for answers, thinking he could copy more. However, Lei Ming discovered his cheating. Jiang Qing Lang had various cheating methods, and Lei Ming started to criticize him. Lei Ming wanted to use this incident to persuade Jiang Qing Lang to join Class 11, but Jiang Qing Lang refused directly.

In the evening, Jiang Qing Lang went to have dinner with his parents. After they entered, everyone stared at their phones. When the mother counted down three, two, one, they all vigorously clicked. These were the mother's friends, and their intense focus was to secure a spot with the most formidable tutor for their children. The tutor only accepted thirty students, and they wanted to secure a spot through competition.

When the parents began asking about their children's future plans, Jiang Qing Lang had nothing to say. Xiao Xiao had been living with her aunt after returning home, and even though she felt a lot of resentment inside, she still did a lot of household chores. On the way home, Jiang Qing Lang's mother insisted on checking his backpack and found many irrelevant things inside. The mother only cared about her son's studies, while the father felt she was putting too much pressure on their son.

An argument broke out between the two, and Jiang Qing Lang's pocket money was also controlled. Xiao Xiao posted Lei Ming's speech from the opening ceremony online, attracting many netizens. In order to retain her fans, Xiao Xiao decided to try joining Class 11. With only one hour left before the registration deadline for Class 11, everyone hesitated whether to join or not. Sang Xia was still worried that no one would come.

Xiao Rui also came to remind them that if they didn't recruit at least five people within a week, the class would be canceled. Lei Ming said there was still one hour left. At that moment, both Xiao Xiao and Jiang Qing Lang voluntarily signed up. As the security guards were about to lock up the teachers of Class 11, Xiao Rui even prepared to have the security guards accompany them with musical accompaniment on their desks and chairs. Unexpectedly, Cheng Yu Shan and Li Ran also came to register.
