i was confused too at first but 'genderless' is just a fashion subculture in japan i think, not nb or x-gender or anything similar? i honestly thought even from the translated name 'androgynous' that there would be a bit more there & it is kinda about gender expression sort of, but you are right that this is just a het couple where the cis ml is an attractive somewhat androgynous model lmao. on its own terms it's decent (even if the characters are a bit flat) but it's basically like any other comfy domestic type series & it never really went anywhere with the gender noncomformist theme

Trow bricks on me idc
But this is like when you try to be woke without doing any research like thats just a het couple... theres nothing too amazing about them, It doesnt even go deep into the GENDER its more like a desconstruct cis het guy, he is confortable with himself and the twink death at the end?
