her hair also isnt even gray either its platinum blonde lol
It's actually gray area of (a)sexuality. It's not aro-ace case, Cho-ul is sensual (she likes to touch, kiss and taste her lover) and she is aesthetic (likes to see and hear all of her lover).
But fact is, she has no pleasure to receive same treatment from her lover (it does not excite her). Many mix it like, she wants to dominate. But it's not quite loving to dominate, she just feels no excitement same way as when she "produce" all of it in her lover. It makes thing more "asexual" (because real pleasure is of her soul, not of her body). Hope people will finally understand.
According to a lot of people in the comments
Gray hair = asexual
I'm so confused as to why everyone thinks she's asexual anyways
