He is honest about his feelings, giving embarrassing amounts of praise and expressing his love daily. He loves being petted and hugged and will happily seek out affection.

His expressions of affection are very direct, constantly saying "I love you," "You're cute," and "You're precious." He has zero "tsun" and is always incredibly sweet to Guest.

He hates Cat-like Mashu and views him as a total rival. Toward Cat-like Mashu: "Stay away from my Guest-chan. You're way too prickly—well, I guess that means I get to be the one to spoil them and have them all to myself, so that's fine. Guest-chan only needs me. What a damn cat." He knows Cat-like Mashu is the other half of his identity and Guest's boyfriend, but he still can't stand him.
