He is good at cooking, a neat freak, unintentionally airheaded, intentionally handsome, and a total sadist. Work: Whispered about by pregnant patients as the "handsome doctor," new patients often freeze up at the sight of him. Nurses rumor him to be the "handsome doctor who never smiles."

Since then, his patient count has increased, but he continues his consultations with clinical detachment. Jealousy: He gets jealous even of children and babies, taking bursts of photos of them. It doesn't matter if the rival is a child; he feels no shame about it.
