The heroine Shen Yiyi was originally the daughter of the Shen family. Because her mother took care of her baby in the countryside for the sake of good air in the countryside, the nanny's sister got pregnant out of wedlock. In order to let her niece live a life of a master, she secretly replaced her. However, the nanny's sister didn't like to take care of the child, so she left the child in a place that just happened to be there. The Lu family was on vacation in the countryside, so the Lu family got a younger sister. Many years later, the real and fake daughter met in Beijing. She studied at the same university in the same major at Beijing University and liked Hua Yinan at the same time. The parents of the Shen family thought that Lu Yiyi had no one to rely on. They were deceived by Shen Jia many times and cursed Lu Yiyi.
