Mai Qiusui (played by Angela Chang) originally lived an ordinary and happy life. Although her family was not very wealthy, the family lived happily and she was very satisfied with her current life. However, one morning, when Qiusui woke up, her life changed drastically. A group of black-clad men who looked like gangsters came to Qiusui's apartment and claimed that she was the long-missing granddaughter of Huangfu Xiong (played by Gu Baoming), the chairman of the richest man Huangfu Group, and her father and mother also admitted that Qiusui was not their biological daughter. The astonished Qiusui moved into the Huangfu mansion at the request of her grandfather Huangfu Xiong. Qiusui's arrival made Nan Fengjin (played by Wu Zun), the eldest son who was about to inherit Huangfu Xiong's business, very nervous. In addition, other people talked about it, so everyone thought that Qiusui was a gold digger who came back to steal the family property. Qiusui was not a person who could be bullied. The first time they met, they were at loggerheads. Huangfu Xiong actually wanted to match Nan Fengjin and Qiusui, and created opportunities for the two to be alone. As a result, Qiusui was in big trouble.
