I definitely could be wrong, but could it be: https://www.mangago.zone/read-manga/failed_to_abandon_the_villain/
I'll have to reread it just in case but I don't think it is T^T it definitely had a name similar to that though. I thought it was "Saving the Villain" but it's not
Looking for a manga similar to "beware the villainess" where a lady Isekais and I think she had brown hair but she has the same dgaf attitude as that FL and there's a villain ML who is obsessed with her and pretends to be nice because he doesn't know she read the original story where he was a psychopath. I only remember the one scene where he keeps her at his mansion because of a music box and nothing else. I read it back in 2020 and wanna reread it
