Yan Song (played by Wang Likun) is a single mother who lives a life of dependence with her son Yan Lang. By chance, the two met an amnesiac man named Qin Mo (played by Liu Kaiwei) in the hospital. Qin Mo insisted that Yan Song was his fiancée and Yan Lang was his son. The kind-hearted Yan Song took in the homeless Qin Mo. At the same time, Lin Qiao (played by Gao Ren), who had a brief relationship with Yan Song, also returned to Yan Song's vision after eight years. Lin Qiao firmly believed that Yan Lang was the result of the "accident" eight years ago, and this time, he was determined to take on the responsibility of being a father. However, what Yan Song did not expect was that Qin Mo's true identity turned out to be the son of the big entrepreneur Chen Tian, and Chen Tian's adopted son Ouyang Teng (played by Huo Zhengyan) was also inextricably linked to Yan Song.
