Ning Jing, who was supposed to have a happy life as a child, left her real relatives for some reasons and lived a poor life with her parents in a rural area in China. Ning Jing didn't have many friends, but she was polite to everyone at her mother's request. Here she had a little playmate, Liu Fan, who later left her. Then she met Lin Yao, a handsome boy in the fourth grade of elementary school. Lin Yao talked to her about everything and almost replaced Liu Fang's existence...
But after Lin Yao left, a series of changes at home made the already silent Ning Jing even more depressed. At this time, real relatives arrive, and everything that greets her is unfamiliar. Can she adapt to such an environment? And can Lin Yao, who is important in his heart, meet again?
