I don't think he's cocky or arrogant, at all. I think he is like me,acting confident and outgoing when I'm in a large crowd/ being taken pictures of. You can see when he talks in interviews that he kinda mumbles a little and shows more in those situations that he's kinda nervous. Personally I don't mind at all, just makes him more adorable!
confident and outoing, yes
but sometimes he can be a little clueless and nervous
he’s not afraid to fool around and pull silly faces
also he’s really sweet with his fans
i think i’ve made my point
