As the saying went, "It's easy to go from frugal to extravagant, but difficult to go from extravagant to frugal." She had been the daughter of the Yu family for more than ten years and had long been used to being a rich young lady. She did not want to give up on a rich life so easily.
Therefore, after Yu Su returned home, she often spoke ill of Yu Su when she was alone with her family, instilling in them that not only did Yu Su want to snatch her identity away when she returned, but she also wanted to suppress and bully her.
After more than a year of hard work, other than her eldest brother, everyone in the family had deeply engraved that thought in their minds.
As long as something happened to Yu Su when she was present, regardless of whether it was Yu Su's fault, her parents and brothers would blame it on Yu Su.
