I guess you could call him some sort of demon, it is basically what he is. You can easily spot it - Which is why he is so sad. He used a long time preparing for this date trying to hide his supernatural flaws as his date does not know that he indeed is not human. He is crying, he had waited for that date in forever, but he can fit anything because of the wings. His blouse want button up, the wings are in the way and he is heartbroken. Imagine being so utterly excited for something that you are unable to do, because you are who you are. Because you don't want to scare this person you've come to care a lot about - You just can't leave for this date you've been dreaming of for weeks.
