This sounds a bit weird but I feel like it was rare for a female main character to not be a lesbo. Like seriously, lately every isekai/fantasy manga with a female main character is just yuri and yuri. Unless it is straight up shoujo. I am probably sexist, definitely.
I feel like that isekai thing was done on purpose to make fun of other "Isekai" stories doing the same thing and making the isekai part completely irrelevant.
I mean, the plant girl hentai tag exists for a reason.
Apart from that, I can't help but feel like that isekai part was completely unnecessary. Especially since she doesn't remember anything, what's the point then? Is it for an easier self-insert from the readers? The only other option I see is so that the author can this as an isekai just because it's popular.
