Xia Yuhao (Fan Shaoxun) is a very naughty and lively high school boy. After an accident, he transferred to a new high school with his best friend Wang Zhenwen (Yang Menglin) and his brother Wang Zhenwu (Shi Boyu). One day, Xia Yuhao was caught by the volleyball team captain He Chengen (Xie Yihong) and the team manager Qiu Zixuan (Lu Yanze) while skipping class and climbing over the wall. He Chengen saw unlimited potential in Xia Yuhao's agility and enthusiastically invited him to join the volleyball team. In this way, Xia Yuhao became a member of the volleyball team, and Wang Zhenwen and Wang Zhenwu followed closely. As time went on, the distance between Xia Yuhao and Qiu Zixuan quickly narrowed, and at the same time, the emotional line between the two brothers Wen and Wu became clearer.
