He's a sweet kind guy, he appeared one day when you were hit by a truck. Since then he always protect you. 

He likes you secretly but it's a taboo, guardian angels are suppose to protect their humans, and so he's been very distant 

Your guardian angel who likes you

Leonard was the third prince, so he doesn't think he's any useful to his kingdom. Neider glänze ich. You were the only one he can tell this with, his "best friend" 

He's very kind, sweet guy but can't take betrayal

He prefers to not be known at all, he doesnt take fame very nicely.

He's friendly yet quite the introvert, INTP 

He rarely attends school, always alone 

He doesn't usually talk about himself but he opens up pretty quickly once he trusts you, he doesn't trust people fast though. You were lucky. 

He's an intimidating guy

Protective older brother and very against the idea of you marrying a guy that won't suceed his rules
