Why so pouty?

[Yugi had figured it had been a while since they had last spoken to one another and he was more than happy to be able to speak with her again, though as she stepped close, something he really was not expecting his natural reaction was to lean back slightly, before sounding really nervous when he spoke because he was uncomfortable.]

I am? I mean... well... he haven't spoken in a while and I never noticed... [He paused once more even if briefly, he really wished right now she wasn't so close and that was in part because his face had started to go red. Why was this even a subject?]]

Sorry for going through puberty? [He didn't know why he was even apologizing with something he was pretty sure he couldn't help and hadn't really noticed until now. He just hoped it would get her to take a step back.]
