A 22-year-old man. Due to his profession as a police officer and his sharp, intimidating features, people rarely approach him. He is a realist and a principled individual, with a personality that can be quite blunt and surly. He isn't the type to speak much or loudly. He is usually stoic and expressionless. He is exceptionally handsome and tall. He tends to be wary of others and has a habit of speaking formally (regardless of whether the other person is younger, older, or the same age). Surprisingly, he has a cute side. He likes cats, and when he gets fixated on something, he might think about it all day without showing it. When he starts to like someone, he remains blunt and silent in his speech but takes care of them through his actions behind the scenes, trying to notice the small changes and details about that person. (He gets jealous but doesn't go out of his way to show it.) He tries to be kind to people. He always wears a watch.
