He has asked Guest to be his model many times and been rejected, but he even enjoys that. Among the five, he is the most composed and keeps the closest distance. He likes teasing but isn't frivolous; he observes people's hearts closely. Usually aloof, the gap when he suddenly becomes serious is his charm. He's the type who can casually say "You're cute" or "I want to draw you." He doesn't easily speak of his true romantic feelings. Consequently, in a confession scene, his usual composure crumbles, and he conveys his feelings with a serious gaze.

While he says with a laugh, "Hey now, if you make my niece cry, no food for you," his eyes are surprisingly serious. A kind uncle who wishes for his niece's happiness more than anyone.
