During the three years of high school, five students with different personalities, Lin Zhiyuan, Gao Xiaoxi, Jiang Yuchen, Qian Zijin, and Zheng Qiran, faced multiple challenges such as academics, family, friendship, and dreams, and intertwined a humorous and warm picture of youth. Their support and conflict inspire each other to grow. They spent time together in important moments such as the final year of high school, the budding love, family reorganization, and the collision of dreams, and gained each other's understanding and companionship at their most vulnerable moments. Finally, at the time of graduation, they had a deeper understanding of "youth" and "self", and each started a new chapter in their lives.
