Harems, are ok, but only if you know the story will end in harem route, when you read romance with harem, you will get one dude and multiple girls who are fighting over him and you have no clue who he will end up with, that is a shitty harem, I hate it so fking much it's insane, but stories like this? The whole point is that everyone basically wins, and you don't have to scratch you head while thinking who is endgame, while it's not anything to write home about, it's fun read for sure.
Also if the other harem members didn't get forgotten. Like some harem mangas have so many women in MC's harem that some of them get forgotten. Also if the MC deserve to get the harem, I hate it that MC is a jerk or a wimpy baby or even a average looking guy like the rest of us and somehow get the girls
Truthfully thats the biggest reason i hate harems. I dont mind polygamous relationships, but the thing is relationships take ALOT of effort. Obviously since its a manga we wouldn't see the nuances, but that doesn't mean it has to completely dismiss it like how a shitty fix it fanfic overlooks how characters will have a different resonse due to a changing circumstance (or like some of the worst transmigation/regression type stories).
And yeah, one massive critic I have about harems is that the women are so indistinct that you can replace them with a fucking sex doll and it wouldn't change their role in any significant way.
Normally I hate harems, but I really love the over the top reactions from this guy and always find milf hunters to be kinda funny in their pursuit of kink.
