In this film, we write about the friendship, love, and family ties of a group of children from a naive and relaxed perspective. Their friendship seems very firm, their love looks very immature, and their family ties seem impeccable. As days go by, they gradually discover that the world is not as perfect as they imagined. Friendships will be betrayed, love is just a cloud, and family ties may also be exploited. . . . . . These are the only ways for them to grow. Childishness - growing up - grown up are the three parts of this novel.
