The CEO's Cleaning Girl is a Billionairess

Lu Beichen and Jiang Wanning met at university and have been married for 20 years. Jiang Wanning has been concealing his identity as the daughter of a wealthy family. In order to take care of Lu Beichen's self-esteem, he does cleaning work and has been silently helping the Lu Group. However, Lu Beichen disliked Jiang Wanning as an incompetent housewife who could only do housework and cleaning, and filed for divorce from Jiang Wanning. By chance, Jiang Wanning saw that Lu Beichen had a new love. He was so devastated that he agreed to divorce Lu Beichen and return to his status as the daughter of the Lingyun Group. After Jiang Wanning had his brain tumor removed, in order to obtain custody of Lu Kai, he and his father Jiang Zhengsheng announced their identity as the eldest daughter of a wealthy family at a banquet of the Jiang Group and inherited the Jiang Group. Lu Beichen regretted it and decided to pursue Jiang Wanning again. Jiang Wanning flatly refused, and finally took Lu Kai with him to travel around the world.
