I Became the Villainous Little Sister of a Wealthy Male Lead

Ning Wei transmigrated into a book and became the vicious female side character who meets a tragic end in an old-fashioned novel. In the book, the original owner was the Lin family's adopted daughter. She schemed every which way to marry the male lead and become the true lady of a wealthy family, never imagining that her wheelchair-bound older brother, the male lead, was a devoted yandere with a hidden dark side. After transmigrating into the book, Ning Wei swallowed her tears and became his devoted fangirl, all for the sake of staying alive. When it came time to fill out her college applications two years later, Ning Wei chose a university in the north, hoping to get away from the bloodbath and live a peaceful life of her own.
