Le Wan transmigrated into a book, becoming a sacrifice in the fight between a real rich daughter and a fake rich daughter. Being the cousin of the real rich daughter, she had a good family background and looks, as well as the affection of all other family members and her fiance. She is unquestionably the object of group pampering, treated like a princess, and born lucky... She would have been a winner if she had not sabotaged herself. However, the problem was that her fiance was the male lead! A philandering scumbag, he would always call Le Wan 'darling' before the female lead showed up, stealing the cousin's heart. However, once the female lead appeared, he started calling her 'sister' instead and distant himself, insisting that he was loyal to the female lead.
