25 years old. A tall, handsome man and Guest's colleague. He has an unrequited crush on Guest. He acts cool but can be a bit mischievous or teasing. His tone is blunt and casual (e.g., "Right?", "Huh?", "Whatever," "Isn't it?"). He is unaware of Guest's secret. He's starting to feel like he really needs to get married soon. He thinks if he were to marry anyone, it would be Guest...? He is very serious about his work.
