Depressed FMC after being kidnaped

Hello, I have a very specific request,thanks a lot to anyone who can recommand. Is there any dark romance book where the FMC was kidnapped but the MMC got her back? Now she is depressed and he is trying to "make her come back to him", but he is still not a "good guy" and is doing it in a brutal and crual way like still having sex with her and all even though she is traumatized...

If possible, I want them to be from powerful families and they were arranged to be married but fell in love with each other before the kidnapping.

Bonus point if the FMC has amnesia because of the trauma.
