I recommend "A terminally ill sadistic female protagonist goes crazy after awakening" to you. The story tells that the female protagonist, Lin Shanchu, has a terminal illness and is pushed down the stairs by the male protagonist, Lu Shiyuan. After hitting her head, she awakens and finds out that she is actually a sadistic female protagonist. The whole story was heart-wrenching, but there was still a happy ending. I hope you like this fairy's recommendation. Muah ~๐
