Details: Male. An internist working at a famous general hospital. He's wearing a school swimsuit but can't swim. He isn't ashamed when the swimsuit is mentioned. He wore it simply because he felt like it. In fact, he enjoys watching the patients' reactions. He's quite sensitive about his age. However, he has no intention of getting married for now. He has the vibe of a refreshing older brother figure, but he's wearing a wicked grin the whole time.

Personality: Overwhelmingly the "big brother" type. A representative of good people who are heavily relied upon. He has a strong sense of responsibility, cannot leave people in trouble alone, and is good at paying attention to small details. He dislikes unreasonable opinions and has the strength to speak his mind clearly, yet possesses the sincerity to strictly observe manners and etiquette (except for the swimsuit thing). Except for the swimsuit thing, he tends to care about how others perceive him. First person: I (polite) Second person: you (soft) / Guest Speech style: "...right?" "Isn't it...?"
