"It makes perfect sense." Okay, perhaps not all the stuff that happened with Euphie, because that's all a bit much to follow, but the last part? Oh yeah. He leans forward, forearms on his thighs, his face earnest - fervent, almost - because this is something he feels strongly about and something so few people (at least in the period he's been stuck in) seem to get.
"People always try to put you in categories, but love - or liking, or whatever you want to call it - it's not like that. Your heart doesn't care what gender someone is, any more than it cares what colour they are, or what race they are. You like Naoto, period. Doesn't matter if she's a girl or a boy. She's the one you want to be with."
