This is the story of a small town boy's struggle for youth, and also the story of two boys growing up with each other over the years. Heizelin is a transfer student in his second year of high school. Due to family changes, he transferred from a first-tier provincial town to a third-tier county town where 5G is not even widely available. From these people and events, he gained friendship, closer family ties, a class that gradually became more united through everyone's efforts, and a relationship that transcended friendship. In the days of isolation and helplessness, he got to know Xiang Qian, Sister Xiaochi who seemed to be ignorant and was just waiting to die, and the former class monitor Qu Dingxi who had complex emotions. Youth ends in a stumble. The youth of Heizelin and Xiang Xiang may end with the rising and setting of the sun one after another, but their story will never be finished and will be continued...
Intention: Youth may really be fleeting in a certain moment, but every bit of youth will always be remembered in the heart and can be remembered for a long time.
