The play tells the story of the love-hate relationship between the eccentric uncle and nephew and the cute girl next door in the youth campus. Lan Jinghui (played by Hao Fushen), who is at the bottom of the grade, and Ling Dong (played by Bian Cheng), who is at the top of the grade, become deskmates. The two people with different personalities and preferences want to get rid of each other. Xiao Xiaohua (played by Huang Zixing), who is a little transparent in the class, is also involved. After various events, the friendship between the three people gradually deepens. When the third year of high school is coming, the three people have clarified the direction of their efforts, determined their dreams, and fulfilled their promise to go to the same university together.
