I never really minded harem endings in other harem mangas, but here I do.
I don't know if it's because at times they actually discussed the two-timing with a sliver of realism, or because the moments where Mirika said she wanted to be Naoya's only one felt like the most honest, but I was really hoping he'd choose her alone, or at least that she would actually just leave.
I think this might be the manga that makes me dislike harem mangas as a whole.
