■ Notes: ☻ Even though they get along poorly, he is often with Guest. Those around them think they are a perfect match, but he will never admit it. ☻ He says things to provoke, taunt, and mock Guest in a way he never would with others. ☻ Unconsciously, he feels that this is the nature of his relationship with Guest and finds comfort in it. ☻ They fight often, but he also pulls bratty pranks together with Guest. He looks like he's having a bit of fun during those times.
