Under Fan Bazhong's design, Ren Tianxing's secret possession of mobile phones was exposed. The captain was very angry that he had betrayed his trust. Early the next morning, Tianxing conducted an in-depth examination in front of the whole class. In fact, he kept his mobile phone secretly so that he could take the pilot test again, but now he decided to keep his feet on the ground.

The boring professional study and training life of the military academy continues. Ye Duoduo’s life has almost been going back and forth between the four points of the dormitory, classroom, canteen, and playground. Since the cell phone incident, Ren Tianxing has worked harder in training and his personality has become more and more cheerful. One of the training items involves crossing the chain bridge, but Duoduo has never been able to cross it. Ren Tianxing offered to lead her across, but Duoduo accidentally slipped and fell. Tian Xing protected her and the two fell to the ground together. Although he was a hero saving the beauty, in the eyes of the squad leader, he was too strong.

But Tianxing is not a fuel-efficient lamp. Faced with the squad leader's rebuke, he is not willing to show weakness. As a result, the two competed in a 400-meter return obstacle course in public. Tianxing was slightly better at the beginning, but he injured his knee at the last moment. After the examination, the doctor performed a minor operation on him, but this time he also let Tianxing know that he would never fly again. The arduous military training is finally over, and Duoduo, Tianxing and others have become official soldiers. At the epaulette awarding ceremony, everyone performed a traditional singing program, and Tianxing also sang a song called "You Are My Eyes."

Listening to Tianxing’s soulful singing, Duoduo couldn’t help but smile as he recalled every detail of the two of them from when they first met to now. After the military training ended, everyone began formal courses. In addition to the courses, they were also greeted by the annual National Day party. Ren Tianxing and Ye Duoduo were appointed to cooperate in coordinating the program. It was originally a very simple thing, but it made Huang Xiaoyue not so comfortable. She went to Liang Zi privately and asked why she, the acting female monitor, was not allowed to cooperate with Tian Xing, the acting male monitor.

In order to appease her, Liang Zi gave her a spot on the program review team. On the other side, the nutritional supplements sent by Duoduo's mother to treat knee injuries have arrived. She didn't open it and handed the package directly to Tian Xing. After all, it was because of her that he relapsed into an old injury last time. Tianxing thanked her for her attentiveness, but when he returned to the dormitory, he found that the package contained not only bruises but also a lot of pajamas. He quickly packed the pajamas in a bag and returned them to Duoduo, but the pajamas had already been seen by Fan Bazhong, who loved to gossip.

The boys were talking a lot, speculating that Ren Tianxing had a special relationship with Duoduo. Liao Fan was very observant and discovered the medicine for bruises, but everyone still thought that Duoduo and Tianxing were secretly crossing Chencang. In the girls' dormitory, there was originally a discussion about Ma Leilei's hopelessness in losing weight, but Huang Xiaoyue suddenly came in and said that Ren Tianxing was looking for Duoduo. Hao Hao, known as the Queen of Gossip, secretly followed Duoduo out and witnessed Tian Xing handing his pajamas to Duoduo.
