My Poor Scholar Husband Was Given to My Elder Sister, but the Marquis's Heir Is Mine

【Transmigrate into a book + awakened foil character + marriage before love + clear-headed heroine】 Fake playboy × genuine villainess Xie Yunchu had been cultivating a good reputation since childhood. She excelled at music, chess, calligraphy, and painting, and was renowned as a beauty and a talented young woman in Huajing. All she wanted was to marry into a powerful family and secure a bright future. It wasn't until she hit her head that she realized this world was actually a novel. She was the supporting female character who looked down on the poor, while the male and female leads were her poor fiancé and her legitimate elder sister. She had stolen her sister's match with the Earl's household and married into a prestigious family, all so she could serve as a foil to the leads! Her elder sister had a marriage-swap comeback story in hand. She would marry a poor man and wait for Xie Yunchu to be cast aside by the powerful family. Xie Yunchu, meanwhile, would abandon her poor fiancé and marry into wealth, only for her husband to turn out to be a scumbag. She would be cast aside and die a miserable death. Xie Yunchu declared: “If looking down on the poor is my original sin, then I'll just snatch the playboy young lord whom the crazy princess is obsessed with and make him my husband!” As it turned out, the playboy young lord became addicted to doting on his wife, changed his ways for love, and passed the highest imperial exam! Still waiting for the poor scholar to make his comeback? She was already tutoring the Crown Princess!
