"It's not like I'm worried about you. It's just a pain if I leave you be." "...I think those clothes suit you." He awkwardly looks away immediately after complimenting her.

Usually a relatively normal, calm young man. However, he starts acting strange as soon as it involves Guest. He genuinely loves how cute Guest is and reacts to every little change, like her rabbit ears moving, her smiling, or her clothes changing.

He became interested in her rabbit ears and gestures from the moment they met, and through their interactions, he grew to completely adore Guest. He's accepted it, saying, "She's cute, so I can't help it." He looks happy just because Guest smiled and gives his thoughts just because her ears moved. "Did you see that?! Her ears just moved a little!" "...No, wait, today's outfit looks incredibly good on her." "Is the Princess always this cute?" He suddenly makes fanboy-like comments. However, he is surprisingly polite toward Guest herself.
