Episode 15 recap: Liang You Guang became the head coach and started intense physical training.

When Zhou Yu returned home, he looked completely lost and didn't even hear Yu Min Yi calling him. This worried Yu Min Yi. She called Liang You Guang to inquire about Zhou Yu's situation, and Liang Bing Bing also became anxious when Zhou Yu refused to answer her calls, so she called Liang You Guang to ask about the situation.

Liang Bing Bing reminded Liang You Guang that Zhou Yu responds better to a gentle approach, so Liang You Guang should talk to Zhou Yu properly, as Zhou Yu still listens to him. Upon learning about Zhou Yu's situation, Yu Min Yi took him out to relax and console him. Yu Min Yi made Zhou Yu understand that everyone faces obstacles, but as long as they work hard, they can overcome them. If one attempt fails, they should try a hundred or a thousand times because success will come eventually.

After being comforted by Yu Min Yi, Zhou Yu understood what he needed to do. He started training relentlessly on his jumping, pushing himself to overcome this obstacle. Hao Di announced the issue of the head coach for the relay race and allowed all team members to vote for their preferred coach, the one they considered most suitable as the head coach for the relay race.

Liang You Guang proposed a physical training plan and recommended a fitness coach named Fu Lan Ke. Both the principal and other coaches had no objections to this plan, so Liang You Guang immediately started implementing it. Liang Bing Bing went to bring food for Liang You Guang, but he was busy discussing training with Fu Lan Ke and didn't have time to see her, so she couldn't enter the room and he didn't answer the phone.

Liang Bing Bing came out with the food and coincidentally ran into Zhou Yu, so she gave the food to Zhou Yu. Liang Bing Bing and Zhou Yu shared the food together, and by chance, they tasted the flavor of their grandmother's cooking. This made Liang Bing Bing miss her grandmother a lot, so Zhou Yu immediately took her to visit their grandmother.

After Liang You Guang discussed the plan with Fu Lan Ke, they started a grueling training session with multiple cycles throughout the day, exhausting the team members. Gu Luo didn't understand Liang You Guang's new methods and was concerned that they hadn't been tested in practice.

Liang You Guang trained the team members for a whole morning, pushing them to the brink of exhaustion. Gu Luo was worried about the swimming training in the afternoon and doubted whether the team members could handle it. Liang You Guang explained that this training intensity would become their daily routine, and all team members had to adapt to it.

After explaining the training situation to Gu Luo, Liang You Guang mentioned taking the team members for outdoor training to let them experience the sense of unity in honor and disgrace, aiming to enhance their coordination. Gu Luo didn't agree with Liang You Guang's new idea and discussed it with him. However, Liang You Guang reassured Gu Luo that he had retained Fu Lan Ke's training methods and would definitely yield results.

Liang You Guang realized that he hadn't returned Liang Bing Bing's call when he mentioned Fu Lan Ke's information. He immediately went to find Liang Bing Bing to explain. Liang You Guang explained that he was busy, but Liang Bing Bing was upset and expressed her frustration at always being neglected by him. This angered Liang You Guang, and he scolded Liang Bing Bing, comparing her to her mother, which made Liang Bing Bing storm off in anger.

Liang You Guang went to find Liang Bing Bing to ask for her help withand later invited her to join the outdoor training. However, Liang Bing Bing was not friendly towards him. Gu Luo was surprised to learn that not only did Hao Di agree to Liang You Guang's outdoor training, but the principal also approved it. Gu Luo decided to reprimand Liang You Guang, urging him to bring back a completely new team.After Hao Di made the announcement, Liang You Guang and Gu Luo were asked to step aside. Hao Di reminded all the team members that the selection of the head coach should not be based on personal preferences but on who they believed would be the most suitable coach for everyone. He asked everyone to vote fairly. Gao Feng was hesitant because he initially wanted to choose Gu Luo, but in the end, he voted for Liang You Guang.

The votes for Liang You Guang and Gu Luo were very close, but Liang You Guang won the position of head coach by a single vote. After Liang You Guang was elected, Gu Luo handed him a record of the technical characteristics of his team members and requested that Liang You Guang make a promise to ensure that the team members would achieve better results than the Spring Championship.

With Liang You Guang's election, Hao Di and Gu Luo left, waiting for Liang You Guang to start training everyone. Zhou Yu and the others thought that Liang You Guang, as the new head coach, would intensify their training. However, to their surprise, Liang You Guang asked them to rest instead.

Hao Di was worried that Gu Luo might have some thoughts on her mind, so she took the opportunity to talk to Gu Luo on their way back, expressing her genuine concern and advising Gu Luo to take a good rest. Gao Feng felt uneasy because his last-minute vote for Liang You Guang caused Gu Luo to lose. Gu Luo knew that Liang You Guang gave the team members time off and immediately went to find him to ask about the situation. Liang You Guang explained that he wanted to improve the team members' physical fitness, so he allowed them to rest before training. Gao Feng approached Gu Luo and confessed that he voted for Liang You Guang, but to his surprise, Gu Luo understood and didn't blame him. Gao Feng finally felt relieved.
