The story tells the youthful time that four high school students, Lin Chen, Gao Yufei, Su Wanqing, and Xu Ziming, spent together in three years. From the ignorant acquaintance in the first year of high school to the tears and laughter when they parted in the third year of high school, they experienced many challenges such as friendship running-in, family changes, ignorance of first love, study pressure, and dream collision. Lin Chen found himself little by little through laughter and tears, and the team became more united after misunderstandings, conflicts and tests. In the end, everyone went their separate ways, and every bit of the past became the most shining memories of youth.
