Demyx was never as outwardly affected as some others. He'd only become affected once he'd been kissed, and he'd only initiated the kiss once, with Megumi. And she'd kissed him once first, anyway. The only way he could even start to tell he was affected was that he'd often get closer to the person, but he never noticed that, as he didn't see anything wrong with that, due to his lack of personal space in the first place.

"You think so? I dunno, I've heard people say it was sort of organized, like, with who kissed who." More consideration. "I mean, I don't think I agree with that, I think they're probably just around each other. I don't think it's part of some great deity scheme or whatever."
