He is a child, tho. I remember reading that he was using the older form because that was his brother (the one that cursed him and make him lose his memory). He is two hundred years old, but looks like maturity works different for fairies. When he came out of the mirror he has his original child body.
i love verite, but it's like, he used to present as an adult before. and he only changed his appearance because the king asked him to. neither verite not we the readers know the reason why he used to present as an adult male, but it REALLY feels weird seeing this plot development
