read the whole comment thread after the manga itself, and it's pretty funny. i'm a cis lesbian reading it because i like the way the main couple are written, it's genuinely really sweet! and i also agree with it being at least subtextually strong on the trans interpretation.
see, there are different kinds of genderbend manga. i've been on dynasty a very long time (account is just new because i never cared about posting), and while i don't go out of my way to read them, once in a while i do. and most of those take the "oh no im a girl now" in either a horny direction or a super heterosexual one (or both). like, super masculine man gets turned into a hot girl and then all of a sudden is submissively fawning over a male character. those are written for cis straight people with a kink.
genderbend manga like this, however, are often an easy hook for closeted trans people (who do very much exist in japan, btw). and the writing of the protagonist does feel like it's leaning in that direction. his life was empty and meaningless before, he's a total weirdo to the other guys and doesn't fit in, and the key point people keep bringing up: he's totally fine with being a girl. i'm cis. i can say with total confidence that if being with someone i loved required me to become a man, i would bail. the idea makes me extremely uncomfortable! but i have close trans friends who feel the opposite, that if there were an easy "instant sex change" button, they'd press it.
like, this isn't to say i know For Sure that's where the story is headed, and i'm along for the ride as much as anybody else here. but it's a valid reading of the story, and i'm curious to see where it'll play out from here. it really does help that the main couple are so cute. i'm surprised i got attached as much as i have
