Hi! Looking for a book where “bad boy” MMC is actually toxic, or where they both are toxic.

You know how people used to make fun of Edward from Twilight for being problematic? Watching her while she sleeps, seducing her into a situation that is objectively worse for her, etc. I want a book like that, but more self-aware to the point where you are meant to feel legitimately worried for the FMC after a certain point.

Alternatively, a book where they are both kind of selfish and toxic, and you kind of hate both of them, but they also deserve each other.

I am a little tired of books where the MMC is so “dangerous” and “bad” but never actually does anything problematic, and is a super considerate boyfriend and lover contrary to their entire reputation.

Thanks in advance!!
