Episode 21 recap: Zhou Yu and Gao Feng went for a trial at the national team. Gao Feng had an argument with Gao Chong.

Hu Jing Tian overheard a conversation involving Liang You Guang and learned that Manager Chen had clarified the situation regarding Liang You Guang. Hu Jing Tian was concerned that the online buzz might not be high enough, so he organized with Zhou Yu and others to create some hype to prevent Liang You Guang from being expelled from school. Zhou Yu and the others believed that now that Manager Chen had clarified the situation, Liang You Guang would be fine, and they should focus on training seriously. After realizing the misunderstanding with Liang You Guang, Zhou Yu happily went to Jiang Ying Ying to share the good news before apologizing to Liang You Guang.

Liang You Guang was waiting for Zhou Yu to apologize, and after Zhou Yu apologized, he showed off in front of Zhou Yu. Zhou Yu wanted to have a drink after apologizing, but Liang You Guang refused and enjoyed watching Zhou Yu while he drank. Liang You Guang announced the good news to everyone, stating that Gao Feng and Zhou Yu had been selected for the national team trial, and if they passed the tests, they could stay in the national team. While announcing the good news, Liang You Guang also reminded everyone that there were many streamers infiltrating the school recently, which had given some players a bit of fame. He hoped that everyone would not let this affect their training.

Everyone celebrated and congratulated Zhou Yu and Gao Feng for making it into the national team. Wu Hao and Hu Jing Tian felt a bit down as they were about to lose two good roommates. Zhou Yu noticed his roommates' sadness and realized that the separation was beginning, which made him feel a bit unhappy.

Hu Jing Tian was envious of Zhou Yu and Gao Feng making it into the national team and lost confidence in himself due to his slightly lower skill level. Wu Hao comforted Hu Jing Tian and encouraged him to keep working hard. After comforting Hu Jing Tian, Wu Hao returned to the dormitory to bid farewell to Zhou Yu and Gao Feng. While Gao Feng was consoling them, they made an unreasonable request to sleep on Gao Feng's clean bed. Liang You Guang and Gu Luo hosted a banquet to celebrate Zhou Yu and Gao Feng entering the national team, and they reminded them to strive to become the best swimmers in the national team.

After a few drinks, Liang You Guang got drunk. While he was happy for Gao Feng, he also mentioned Gao Feng having to face Gao Chong in the national team, which instantly dampened Gao Feng's mood. Gu Luo noticed Gao Feng's unhappiness and stopped Liang You Guang from saying more. He privately comforted Gao Feng, advising him not to put too much pressure on himself.

Zhou Yu and Gao Feng set off, and Gu Luo went to talk to Wu Hao to see what he thought. Wu Hao believed that Hu Jing Tian was a good talent and suggested Gu Luo pay more attention to him.

Zhou Yu embarked on the journey to the national team with a lot of anxiety in his heart. He worried about not being able to stay in the national team and missed his loved ones who he was about to leave behind. Liang Bing Bing continued her equestrian training, Jiang Ying Ying was considering whether to go abroad, and Yu Min Yi was still busy with her noodle shop, constantly reminding Zhou Yu, which made him miss them even more.

Wu Hao became Hu Jing Tian's second coach, and with Wu Hao's help, Hu Jing Tian began to make progress. Zhou Yu and Gao Feng arrived at the national team and witnessed the grandeur of the team. They were even more grateful for the opportunity to enter the national team, which strengthened their confidence in wanting to stay.

Wang Ji Fei was waiting for Gao Feng and Zhou Yu to report and was eager to compete with them. The other national team members started discussing them because Gao Feng was Gao Chong's son and Zhou Yu was an eye-catching dark horse. Zhou Yu was tempted to get into a fight.

Soon, the testing at the national team began. Zhou Yu and Gao Feng gave their all but still didn't achieve the best results. Fu Xin had good swimming skills but lacked physical fitness, while Zhou Yu was good in all aspects, except that he struggled a bit with distances over 1,500 meters, unlike Fu Xin.

Gao Feng always felt pressured when facing Gao Chong. Due to a late start and not being in a good state, he didn't achieve outstanding results. Gao Chong was particularly unhappy when he found out. Gao Feng was discussing entering the national team with Zhou Yu, but he wasn't happy about it and felt that being in the provincial team was more relaxed.

At this moment, Gao Chong called Gao Feng and berated him for his poor test results. He also mentioned that Zhou Yu was catching up to Wang Ji Fei, which greatly upset Gao Feng. Gao Feng, angry after hearing Gao Chong's words, finally couldn't help but express his desire to quit swimming and blamed Gao Chong for never seeing his progress. He always remained the underachiever in Gao Chong's eyes, so he didn't want to swim anymore.

After the argument with Gao Chong, Gao Feng messaged Gu Li to vent his frustrations. Gu Li's comforting words relieved him a lot. Wang Ji Fei went to find Zhou Yu and revealed the reason why he liked swimming and started learning it was because of Zhou Yu's father. Zhou Yu understood the reason why Wang Ji Fei cared about him and realized that it wasn't personal.
