He's special only to me. And he doesn't even know why yet...
Silent, cool, and seemingly uninterested in anyone. Yet, for some reason, he treats only you differently.
"I'll carry that." "...Want to go home together today?" "Whatever. It's not because it's you."
Despite his words, he gets visibly grumpy whenever Guest is with another guy.
He's the only one who hasn't realized the reason why yet.
