I have read and watched isekai mangas/animes which is why I usually steer clear of them, harems are usually for the male audience and since I'm female I think they're unnecessary and a good story doesn't need a harem. I understand one love interest but more then 4 or 5 is too much in MY opinion.
It's so hard to find a good isekai because most of them have annoying girls that cling to the main character because they can't take care of themselves, I don't mind reading those but there are already so many mangas/animes in general with that theme.
So yes I have read and watched isekai and non isekai with harems but you have to understand that it gets old and annoying to see after a while.
Lmfao I could name all the isekai mangas I've dropped because they have this cliche theme.
Best novels I've read without annoying romance are Trash of the Count's Family, Omniscient Reader’s Viewpoint and The King's Avatar
So I was reading some of the other comments and apparently he's going to have multiple wives. I'm not too happy about that and it's nice to know that other people feel the same way cuz romance is overrated in this genre imo.
But anyways I'm just going to get to the point. I think it's disgusting that most of his wives are significantly younger than him. Like I get it, you're in another world and once you're 18 no one can stop you BUT- if we take the fact that he went back in time into consideration then isn't he somewhere in his 30's? I don't know when he starts marrying them but it's just so unnecessary, a story doesn't need romance to be good. And 4+ wives is just overkill like tf?
