[That sounds fake but okay, whatever-- it doesn't seem like Aoba is lying, and there's definitely other weird stuff here. He's just filing it away as yet another one of those things- and also as a problem. He folds his arms as he frowns up at Aoba.]

Well, you're not gonna be able to do much if you don't do something with it. Isn't it easier for people to touch it if you just leave it like that?

[And if he's going to be sharing that pain... ugh. Yeah, it's a problem. Just to make his point, he braces himself for it (now that he knows it can hurt him, too) and quickly leans in to flick at Aoba's hair.]
