The label for asexual means someone who doesn't experience sexual attraction, work with me this will all tie in. But underneath that term, people who claim it can still like and have sex. You can have ace people who are disgusted by it to those who actually still want it. The label is a blanket term. And one experience differing drastically from another doesn't change the fact that the person is still asexual. Same with aro. She is labeled aro because she doesn't experience romantic attraction. That does not mean what she feels for Chris is the same thing she feels for a romanced Roe. That does not mean that what she feels for a romanced Roe is the same thing she feels for Roe who is only a friend. Just because she does not hold the normal societal views of romance as her own, does not mean there is not a deep connection between her and Roe. Otherwise, she'd be f****** (can I cuss on here) friend Roe and that doesn't appear for reasons she herself says. Therefore, she is romanceable. If that was not the case and she treated everyone the exact same, she would not be.
There's a whole lot more to be said about aromantics, but I cannot solely educate on that as my experience with being aro won't match another's, like theirs won't match another persons. But the big idea is that it's a blanket term that can be stretched and modified and changed. Hopefully that helped in some shape or form.
