Chongdi High School has welcomed a new student. Liu Fuli struggled for a year and finally got admitted to Liu Guang, the best class in Chongdi High School. However, the good students here were not what he thought, and they did not look like good students at all. The quiet Ye Xiaoxu, the strange Hao Mulan, the funny Lin Xiaozeng, the troublesome Su Zuoyi, and the daydreaming Dong Jinhuan just entered high school life, but they faced huge changes in friendship, love, and even family ties. Cooperation, use, betrayal, and conspiracy overwhelmed them. After experiencing separation, they finally discovered that the original innocent friendship and love were still there.
