In a senior high school in an emerging city in the south, five high school students with very different personalities became friends by chance. Each is burdened with academic pressure, family expectations, dream difficulties and youth confusion. They gain precious friendship and love through conflicts, misunderstandings and joining hands. The story runs on multiple lines, from family changes, love emotions to the ups and downs of self-expectations. Du Chenyang grew up in family and self, Lin Zhiwei pursued freedom amidst shackles, Zhao Yufan tempered his dreams in frustrations, Chen Xiaomeng found belonging in loneliness, and Li Ruochen healed his pain with art. After three school years, multiple transitions, and their respective growth, they finally gained the courage to face the world on the eve of the college entrance examination, and joined hands to move towards their new life stages. Youth was endowed with unique meaning and profound imprint.
