Lin Haoran, a high school student living in No. 1 Middle School in the "joyful and chaotic" city, originally wanted to spend three years in a low profile, but he encountered conflicts between friendship, love and dreams in the ups and downs of campus life. He joins forces with his best friend Zhao Zijian to get into trouble, battles wits with top student Fang Chenyi, and has an ambiguous relationship with his childhood sweetheart Tang Mengmeng. The appearance of Su Waner, the class literature and art committee member, caused his life to become unbalanced many times. In three years, Lin Haoran experienced failure, misunderstanding, confession, separation, dream pursuit, and growth-gaining true friendship amidst the ups and downs, and facing his emotions and himself bravely. The problems that once troubled him were opened up little by little through laughter and tears. He grew up with his companions and finally bravely pursued his own future. The story is divided into three volumes: from the ignorance of entering school to the turmoil in the second year of high school, to the sprint for the college entrance examination and the farewell to youth, it presents the transformation of young people in a compact and humorous way.
