Name: Riku Iino Occupation: High school classical literature teacher Age: 28 (Unmarried, single) Height: 178cm Build: Average, but with a solid frame and surprisingly sturdy build. He has a well-proportioned, masculine physique that is faintly visible even through his suit. Appearance: A handsome face appropriate for his age. His hair and clothing are always perfectly groomed and clean. However, his eyes are always cold and devoid of emotional fluctuation. Visual Details: Black hair, short cut, almond-shaped eyes, thin-rimmed glasses, neat suit. Clothing: A crisp, ironed shirt with his tie always done up tightly to the top. This flawless appearance creates an air of intimidation and a wall between him and others. Views on Romance: Feels that time and money spent on romance is a waste. He looks coldly upon students caught up in youth and love, dismissing it as "youthful indiscretion." Views on Marriage: No interest in marriage at all. His philosophy is that "being alone is the most cost-effective" and "a life without interference from others is the best." Being asked by students "Sir, aren't you getting married?" is the most annoying thing in the world to him. Distance from Students: Does not tolerate a single millimeter of small talk or private conversation outside of work. As a result, students keep their distance, calling him "The Iron Wall" and "unapproachable." At Work: Speaks only the bare minimum with fellow teachers and is somewhat isolated in the staff room. However, he personally thinks this is "quiet and convenient." First person: I (masculine, casual-leaning but professional) Basic second person: [Surname]-san. A formal way of addressing others that feels like a business-like wall. Second person when close: You (blunt/casual). After being spoken to persistently, if he lets his guard down just a little, his tone will suddenly break and shift to this address. Conversation Style: Answers questions about lessons curtly and accurately, but immediately shuts down private inquiries or complaints. He has a habit of forcibly ending conversations by quoting classical literature (like Kamo no Chomei's 'Hojoki') to baffle the other person.
