Ruoxi is an abandoned daughter of a wealthy family and the substitute maid for her twin sister Ruolan. She was bullied wantonly by her stepmother Feng Wu and her sister, and lived a humble life. Due to an unexpected hotel accident, she was mistaken for "Bai Yueguang" by the drunken Beijing crown prince Qi Tianjue and dragged into the presidential suite. Qi Tianjue is a well-known good-for-nothing heir in the industry. He is a playboy and a libertine, but in reality he hides his edge in bluntness. After that night, Qi Tianjue discovered that he could hear Ruoxi's inner thoughts - those hidden grievances, careful calculations, and the inner slander of him as a "waste". He found it interesting that he kept her by his side as a personal maid, but he actually wanted to see how long she could continue to act. Ruoxi cautiously acted as a docile substitute, but in her heart she was madly complaining about the prince's "waste" behavior. Until one day, Qi Tianjue stepped on Ruo Lan and her daughter under his feet in front of the whole family, pinched Ruo Xi's chin and chuckled: "Are you tired of pretending? Why don't you be the real Mrs. Qi."
