Four people, Shen Zhiqiu, Zhang Xiyi, Lin Chuchu and Xie Yin, live in the same street. However, they have different family backgrounds and have established a deep friendship. The four people's high school is full of joys, sorrows and joys. From campus to life, from friendship to family ties, there are no twists and turns. Even if something happens to Zhiqiu's family and classmate Li Lingyi provokes them everywhere, no matter good or bad, they always have each other by their side. Over the years, we have never left, and we have experienced our spring, summer, autumn and winter together.
