I get that it's supposed to be vague, but I think I've settled on Jun being the natural male, just timid and Kaoru being the natural female, just a tomboy. I also get that it should kinda be obvious because of their names but they threw me through loop near the beginning, I honestly couldn't keep track for a while until now.
Anyway, I've enjoyed this hell of a lot more than I thought I would. It seems like it's been a while though so I hope it updates again soon and doesn't just die off.
I truly wish more genderbend manga handled things this way. I read these because the situation is genuinely interesting to me and it feels like most genderbend manga will stick with the shenanigans for a couple chapters before instantly dropping them after, not bothering to address how the main character is still adapting their whole life to it.
Bit of a rant but tl;dr of that is I like this a lot and wanna see more. Will gladly take other genderbend suggestions similar to this if anyone has any. Feels difficult to find them of this quality.
