I think -harem- tag is often misunderstood, it doesn't mean HAREM END / poligamy / multiple wives (things that people have some kind of prejudice towards, just like -loli- or -incest- tag... seen by MD comment section in series with those tags and their rating)... it just means that two or more girls will be interested in the MC, just that, even if the MC doesn't give a sht about them, if two waifus are into him, that is already seen as a "harem" manga.
99% of the mangas with the harem tag out there doesn't end in harem end and go by the 1 waifu end or hand waifu end.
@Novak_Vai If you "yeet" yourself out of some manga with that tag because "that male will marry X females!"... yeah... harem tag doesn't mean that.
