Prompto was thinking, sure. Thinking with his hand in his face, about how anyone at the party last night that might have paid any attention to him (which he hoped was not the case, no one ever paid attention to him, right? So why would it be any different last night?) would have known that this was clearly not anything new for him, except the whole part that it was definitely new for him in a classroom setting, and there were people in this class that he was definitely not emotionally or spiritually prepared to be watching naked people doing things to each other with.
