Well I think that the author means with the no harem tag is that there probably gonna be a LONG time skip (there's no way that the author is gonna show us all the years he has been through) probably a few quindecillion years later in which the main character says that he had alot of girls and harems but discarded them all but still stayed with the main love interest.So technically he had a harem but they were in a time skip and weren't important to the story cuz only the main love interest was. Of course it's all up to the author of course also two stars for a simple stupid harem problem you seem like a okay guy but still the story etc etc was all very good but that's only like two stars? And like a stupid harem thing is like an entire three stars off? Your a decent guy but your harem fetish is a bit too much bud. Anyway that's all sayonara bye bye hastalavista I'm outie here
