In the early autumn of high school, Lin Mo quietly entered the new school and faced a new environment. He met the sunshine girl Ye Qing, his best friend Su Ye, the mysterious transfer student Jiang Yuan and the gentle class monitor Tang Youran. The five people accompany each other and grow up in a series of daily chores and youth challenges. Their mutual friendship and youthful secret love once caused misunderstandings, but they also made them learn to cherish amidst loss and joy. Through family conflicts, academic pressure, dream pursuit and farewell, they finally found the direction of their lives - learning to face changes, bid farewell to the past, and rush to their own distance.
