Zhong Dahai, the captain of Mingde basketball team, turned into a girl at the critical moment of the college league?! The attending doctor thought her case was very valuable for research, and promised to help her find a way to turn back into a boy, and helped her to register as a transfer student under the pseudonym Zhong Yanxin. The basketball team, which had lost its mainstay, was on the verge of disbanding, and Zhong Yanxin had to turn to her childhood sweetheart Lu Xingqi from the same school for help, but was teased by him. Lu Xingqi's attitude was mean and venomous, and he was not the righteous good brother in his impression. Zhong Yanxin was shaken in their friendship, and finally Lu Xingqi agreed on the condition that Zhong Yanxin became a cheerleader. Zhong Yanxin endured the humiliation and put on the cheerleader uniform, becoming the focus of the audience, and the basketball team finally got on track. Zhong Yanxin was dissatisfied with Lu Xingqi's malicious teasing, and felt that he could no longer treat him as a brother like Zhong Dahai. The two were tit-for-tat in the team, and small quarrels continued, but Zhong Yanxin found the familiar feeling of brotherhood in one game after another, and found that he had a different mind for his good brother.
