Looking for a story

A girl got transmigrated into a body of a princess or a villainess I think? She fell in love with and npc so she doesn't want her fiance anymore. Turns out the fiance is psycho and his life is literally programmed to be seen as someone that never does wrong. So when princess rejects him, he got obsessed with her and raped her over and over again. Detained her in the bedroom, doesn't let her out, and made her addicted to sex with him. Also the original female protagonist turns out to be a sadists that luvs to torment masochist men. Anyone got link?
