^Yeah, here it worked really well, unlike The Big Bang Theory where they made Sheldon semi-officially autistic because he fits autistic stereotypes (ugh).
Shamiko's pantyhose is pulled down, Momo's hands are active around her tummy, one moving down, the other under and up. I'm frankly amazed this doesn't have an ecchi tag
Maybe they just think that Fern x Frieren yuri is good birthday gift, I'll personally like it. Or maybe it was just a joke, and everyone should take all of this a little less seriously. Very nice picture by the way.
^Going into a lesbian/LGBT centered community and commenting that you're going to self insert into a male character in order to receive a woman as a present is weird. It's weird for a few reasons but at the very least read the room here. It's entirely reasonable for people to be uncomfortable about such a remark and it's not something that people should simply "take less seriously" as you put it.
