This is the three years of high school for a group of "problem" teenagers: they have experienced misunderstandings and reconciliations, secret love and growth, ideals and losses, family changes, misunderstandings between teachers and students, academic competitions and reunions. Playing in laughter, crying in the corner of campus, and walking through the troubles of youth together. On the graduation night of senior high school, they reconciled with each other and embarked on an unknown life. In simple and real daily life, there are the most devastating crying and the most joyful laughter - that is youth.
