This isn't the fist manga I've read where I can't tell if they mean "just" asexual or aromantic and asexual.
Though I guess from my extremely limited research they seem to use "asexual" to mean aro ace and there are different terms for the orientations separately.
O he's in hight school instead of being 20+ like the webcomic version lol
I'm kinda glad though in case they try to make any feelings seem mutual in the future so it's way less weird. I will miss the one sided crush aspect though it was kinda sweet.
