She's actually from a wealthy family

Gu Yunxi wants to tell her pregnancy to Fang Yichen, her husband. But she finds him with Liu Yuru, who is pregnant. She decides to ask for a divorce after receiving abuses at her mother-in-law's birthday party that she hadn't faced before. Gu Heng, her older brother, shows up right on time to drive her home. Gu Yunxi unexpectedly meets them again when she is asked to be the host of the business event. Liu Yuru tries to embarrass Gu Yunxi, but she responds firmly. Many people mistakenly think that Gu Yunxi is Gu Heng's mistress, which causes the Fang family to treat her badly. They realize how badly they treated Gu when they know that Gu Yunxi is the daughter of the Gu family. However, their relationship cannot be repaired.
