Episode 8 recap: Lei Ming asked the math teacher to come back and teach a math class.

While everyone was taking a nap, Lei Ming used singing to teach English to everyone. He even closed the curtains, creating an environment that felt like a KTV (karaoke) room. At first, everyone couldn't resist the urge to study, but eventually, they all started singing along. Li Ran was a bit shy, and Cheng Yu Shan joined in singing. Even Sang Xia, who was outside the door, started bouncing and singing along.

Lei Ming wanted to make everyone enjoy English through this method and show them that English is not a complicated subject. The next day, when everyone was getting ready for class, a teacher arrived with a suitcase. This was the math teacher Lei Ming had invited. Initially, the teacher wanted to leave upon seeing that there were only five students, but Lei Ming stopped him.

The teacher wasn't even proficient with computers. Li Ran, as the class monitor, went to the front and inserted a USB drive for the teacher. The teacher's name was Hu Chong, and he was Lei Ming's former teacher. Hu Chong was known as the "Chinese question bank" because he had seen all the exam questions. Initially, everyone didn't believe it, so they found an old set of college entrance exam papers from many years ago. After glancing at them, Hu Chong quickly provided the answers.

Jiang Qing Lang was searching for the answers nearby but couldn't keep up with the teacher's speed of response. Lei Ming had initially approached Hu Chong, who refused at first. However, Lei Ming deliberately tempted him with the number of students who had been admitted to top universities, which was something Hu Chong cared about. Lei Ming also mentioned that the five students in his class were carefully selected and had the potential to succeed.

The first thing Hu Chong did when he arrived in the class was to conduct a diagnostic test. Only Cheng Yu Shan was able to solve it easily. Li Ran took the lunch his grandmother had prepared and brought it to Shen Yao, who then humiliated him. The students of Class 11 witnessed this. In fact, two days earlier, Yu Yang had been bullied by his former classmates, and Shen Yao asked them what benefits Li Ran had given to them.

In the evening, Li Ran found Lei Ming. Lei Ming knew that Li Ran had a kind heart but was reluctant to express it. He then asked Li Ran to send a message to everyone using his phone. When Li Ran received the phone, he saw a missed call and quickly called back. Li Ran hurriedly ran to find Lei Ming. It turned out that Lei Ming had been trying to help Li Ran recover the money he had been cheated out of and had been visiting the police station every day. Finally, the money was retrieved.

Lei Ming went to the police station every day to seek help with the money issue. Li Ran also noticed that Lei Ming genuinely cared for him, but even though words of gratitude were on his lips, he held them back. Soon, the fourth day of training arrived, and Bian Xiaoxiao was called over by so-called friends who wanted her to create an opportunity to prank Cheng Yu Shan. They also made false promises to Bian Xiaoxiao, who, in order to please them, reluctantly agreed.

Jiang Qing Lang's mother was reluctant to let him join Class 11, but she respected his decision. Bian Xiaoxiao, with the so-called friends' prepared phone, intended to capture everything happening in Class 11. Jiang Qing Lang became increasingly happy as he played along. At that moment, Jiang Qing Lang's mother arrived, and together with Jiang Qing Lang's parents and the school principal, they went to find Lei Ming. As a member of the parent committee, Jiang Qing Lang's mother naturally disapproved of Lei Ming's teaching methods. Sang Xia informed Jiang Qing Lang's mother that he hadn't played with his phone for three days.

Lei Ming also stated that if Jiang Qing Lang could score above 90 in the test after ten days, he would let him stay in Class 11 since Jiang Qing Lang's usual English score was only around 70. Finally, the principal allowed Jiang Qing Lang to decide for himself, and Jiang Qing Lang chose to stay in Class 11. Reluctantly, Jiang Qing Lang's mother agreed.

Jiang Qing Lang's mother still wants her son to return to his previous class, but Jiang Qing Lang wants to give it a try and see how far his abilities can take him. While everyone was sleeping at night, each person was engaged in their own activities, and Bian Xiaoxiao secretly live-streamed everyone's actions.

Jiang Qing Lang wanted Yu Yang to help him cheat in the exam, but Li Ran disagreed with the idea. Cheng Yu Shan also discovered Bian Xiaoxiao secretly filming, and Jiang Qing Lang came forward voluntarily to explain, stating that he had also noticed that Bian Xiaoxiao was being threatened.

Soon, a dispute broke out among everyone, and Jiang Qing Lang and Li Ran ended up getting into a fight. Yu Yang tried to intervene, but ended up getting injured.
