The Unrivalled Lady from the Lin Family

Lin Xi discovers that her struggles, poor grades, and self-sabotage are caused by a binding system: the sadder she is, the more successful the poor student Li Sisi becomes, while her childhood friend and fiancé relentlessly force her to endure hardship for Li Sisi. After realizing the truth, Lin Xi decides to break up with the scumbag, cut off the blood-sucking relatives, and choose to give up. Consequently, her perfect looks, ideal figure, and vast knowledge return one by one, while the once-glamorous Li Sisi begins to become ugly, fat, and foolish.
