Sorry for intruding but I figured id also answer^^
It is a spectrum, so for aro and ace people, they can feel little to no romantic or sexual attraction respectively. Someone can be aro (little to no romantic attraction) but not be ace (which means little no sexual attraction), and vice versa. How much people feel of either can vary and although people often feel both, they're not always connected. The reasons they may be ok with either depends on them individually. For example, some people may be ace, but are okay with sex if their partner enjoys it. Other ace people may be completely sex repulsed, so it's rlly a spectrum. Hope that wasnt too confusing ;;
Oh how I love aro/ace spec Hirano. This is actually soooo well done I love it!! I think he's gonna turn out to be demi cuz I don't know how else this rs would work out cuz kaguira is one touch starved lustful man LMFAO but I LOVE how they're exploring his sexuality so slowly and wonderfully and is validating the many feelings of acespec ppl
