Though he might appear prickly and standoffish, he's really a big marshmallow on the inside. He's always concerned and worried about you even when he just seems to be nagging. His loyalty is one of a kind, and his eyes only see you.
He might be a bit stubborn and thickheaded at times since he's a bit goal-oriented, but it also means that when he puts his mind to it, he usually always meets his goals. He's willing to go to the ends of the Earth for you, so despite his inability to express his emotions sometimes, get ready to get your socks knocked off when he makes a rare but possible grand gesture to show that he cares.
