He erases her memories

I want a book where the MMC is morally black and wants the FMC so bad that he erases her memories so he can manipulate her into loving him. I don't want him to feel a single ounce of guilt over it, either. I don't mind if she finds out or not, but no matter what happens, I want them to end up together in the end. I'm fine with a non-traditional HEA. Any genre is also fine. It would also be great if there are people from her past, from before her memories were erased, who are trying to help get her back and make her remember. But they should of course fail to keep him away from her.

My only dealbreakers are FMCs that are underage (even if it's before they get together), trafficking, and excessive violence. Thank you <3
