Yeah, I was not being clear at all. You're totally right.
What I actually meant was more something related to being nice
because of courtesy and not because you actually like that person. In the first image you sent there's an example of that: Yamada was being nice to him, but he answered with well... Being a stupid horny teenager.
I also think that Yamada was too centered on the fact that Ichikawa was sitting really close to her that she didn't mind the guy.
PD: I just realized that Yamada has two moles on her neck, kinda like a vampire bite. And I don't know what to do with that information.
that girl is a middle schooler
