I know Dina doesn't have a phobia or concern about taking off her hat, which is part of why it bothers me that Becky hasn't directly asked. Now they're in a class but they were alone earlier. The only thing making it weird, in a bad way, to me is that Becky feels like she needs to use other ways when she has the ulterior motive of
"taking the next physical step in the relationship". The next comic Becky is straight up talking about it being sexual to her. In those terms, seems like the kind of thing the people in the relationship should openly talk about instead of forcing it to happen out of context for one of the persons.
Makes me think of situations where Person A has a foot fetish and asks Person B, who doesn't know A has that fetish, for images or contact with Person B's feet. Person A might even say, "What? It's just feet. It's not like I want nudes." Although that's a bit more extreme and there's the benefit of this being two people in a relationship.
I'm not that squicked but I do also hope this resolves soon.
Edit: I realise Neko-Ali's might have been meant for Kugai afterwards. Whoops.
