Episode 5 recap: Yu Yang successfully joined Class 11.

Since childhood, Yu Yang had a slight stuttering problem, so he was often mocked at school. Since childhood, Yu Yang had felt inferior because of his stuttering. Even in high school, he was constantly teased. One day, while Yu Yang was changing pants during a physical education class, someone secretly took a picture of his underwear and posted it on the school's confession wall, so the entire school saw the message.

At that moment, Yu Yang's mother came to find Sang Xia. Because Yu Yang's mother wanted to take care of her son, she took over the school cafeteria. She also brought Yu Yang to Lei Ming's class. Lei Ming had already been mocked by many classmates, so he was very nervous when Yu Yang came to his class. It reminded him of his own childhood experience of being mocked for stuttering. Yu Yang couldn't even complete a sentence.

Lei Ming directly said that Yu Yang didn't meet his admission criteria and wanted to reject him. Lei Ming suppressed Yu Yang and even shouted at him, asking why he wanted to study. Li Ran and Cheng Yu Shan stood up to refute Lei Ming. In fact, Lei Ming wanted to force Yu Yang to express his thoughts and help him overcome his stuttering problem as soon as possible.

Lei Ming said there would be a diagnostic test in the afternoon, and if Yu Yang could pass it smoothly, he would agree to let him join Class 11. During lunchtime, everyone was eating in the cafeteria, and Yu Yang was preparing for the afternoon test. When Yu Yang's mother saw her son, she quickly pulled him to the front row and served him a lot of food. Yu Yang became nervous again, as he didn't want to be the center of attention.

While Yu Yang was alone on campus, a girl approached him and greeted him, but then someone directly took off his pants from behind. Yu Yang was once again bullied, but he didn't tell his mother about this incident. His mother always emphasized the importance of studying and told him that he didn't need to handle anything else, not even undressing himself. In front of other aunties, his mother would wipe his body, and even though Yu Yang felt uncomfortable, he dared not say a word.

Soon, the afternoon test began, and everyone was writing fervently. Jiang Qing Lang was the only one who peeked at others' answers. As the time to hand in the papers approached, Yu Yang became increasingly nervous, but Sang Xia took the initiative to comfort him. As everyone handed in their papers, only Yu Yang remained. As soon as the time was up, Lei Ming quickly graded all the papers, and the results were announced. Yu Yang thought he couldn't stay and was ready to leave.

However, Lei Ming told everyone that the test scores were for him to assess their abilities to get into Tsinghua University and Peking University. In fact, Yu Yang had always been among the students Lei Ming was preparing to train. Sang Xia felt that this was too harsh on Yu Yang, considering that he was sensitive.

Lei Ming also told everyone that for the next ten days, they would undergo a short-term intensive training, so they would have to eat and stay at the school. Lei Cheng Yu Shan went home in the evening, and Bian Xiaoxiao actually lived nearby as well. After returning home, Bian Xiaoxiao told her classmates about what happened in class. Although it seemed harmonious on the surface, Bian Xiaoxiao also had a protective shell in front of them.

Bian Xiaoxiao formed a group of five people, consisting of the current five students in Class 11. Cheng Yu Shan's stepfather overheard her conversation with her wife, where her wife asked why Cheng Yu Shan had changed the lock on her room. Cheng Yu Shan had actually done it to prevent her stepfather from entering her room again.

Upon learning that Cheng Yu Shan would be attending the ten-day training at school, her stepfather naturally disagreed. Just then, Sang Xia called, and she asked Cheng Yu Shan to put the call on speakerphone, successfully convincing her stepfather to allow Cheng Yu Shan to participate in the training.

Lei Ming and Sang Xia appeared to be shopping for training supplies at the supermarket, but Lei Ming was actually taking various photos with his phone. He planned to send them to his elementary school classmates to get discounted items. The supermarket had trial-sized products, and he planned to take them all. Jiang Qing Lang was packing his things at home, and his father actually understood him very well. It was only his mother who always had a strict attitude towards him. Jiang Qing Lang knew about it but didn't dare to speak up.

Li Ran wanted to use the IP address to find out who was responsible for posting Yu Yang's photo. Unexpectedly, it turned out to be Shen Yao. During dinner, Li Ran directly climbed onto the table and confronted Shen Yao, asking him to delete the photo. Shen Yao pretended not to understand, but he was actually nervous. Shen Yao even deliberately threatened Li Ran by mentioning his grandmother's job. Li Ran didn't dare to say anything further. The reason Shen Yao targeted Yu Yang was because of an incident during a lecture many years ago. Yu Yang had an upset stomach and accidentally defecated on Shen Yao's shoes. Since then, Shen Yao had been intentionally bullying Yu Yang, as others also found him smelly and avoided him.

Shen Yao had a secret as well. He frequently self-harmed, but only Li Ran had accidentally witnessed it.
