Lin Zhile, who has always been active in the class as a "joker", welcomes transfer student Cheng Yusheng in the new semester of high school - with outstanding grades but a cold personality. As bizarre incidents occur frequently among classmates such as Su Chenyu, Jiang Xiuxiu, and Zhao Jiabao, everyone grows together under the pressure of study, competition, emotions, and family. Friendship, secret love, misunderstanding, dreams, the collision of ideals and reality interweave a colorful campus memory. Three years of campus life were full of ups and downs, and everyone faced their own challenges. Finally, they completed their own transformation in the senior year of high school, lighting up each other's youth. The humorous story is interspersed with tears, the rhythm is tight, interlocking, and finally has a happy ending.
