You reply doesn't make sense. I wasn't implying that the story has no or should not have 'harem'. I was just hoping there was a tag for 'no harem' and apparently there was (not related to the story, just in general - which I mean the Light Novel Pub).
Moreover, we know what 'harem' leads to even if there were no 'romance' tag. And personally, I hate it. I'm not campaigning for feminism here but I disapprove of sexism and most novels especially those with harems are very sexist. It's quite appalling.
