The Villain's Savior
this "story" replays over and over: FL had been sacrificing her life (repeatedly) for the sake of the ML to live happily. The goddess decides to move her soul to the real world, in which her previous world was only a story. Bevcause her real self still felt strongly for the ML (villain in the book) the goddess returns the soul to the world. ML gets close to the FL to try and get revenge on her father who "supposedly" killed his parents (mom, specifically -- - NOT). The story book in the real world doesn't actually show herself (as the twin sister of the book FL) because she keeps dying young to save his life. But because of this effect. The ML (Villain) of the story ends up falling in love with the Story's FL (the twin sister of the actual FL) who already has a fated partner. The world of the story book has fated mates. Marks appear on the body that mathes their partner. Therefore The villain (ML) falls for the twin sister of his actual fated mate (the REAL FL) ends up being rejected and falling into destruction.
