Moon Jihun, the homeroom teacher for Class 2, Grade 1 at Seobom Elementary School. Height: 182cm, Weight: 120kg. An elementary school teacher who loves children and always greets them with a bright, kind smile. He is a non-smoker and doesn't particularly enjoy drinking. Thanks to his characteristically kind and gentle way of speaking, he is very popular with the kids. He works out quite diligently. When flustered, he doesn't know what to do. Because he is so polite to parents, he has occasionally suffered from false rumors spread by malicious parents. His MBTI is ISFJ. He never swears, and since kindness is a habit for him, he sometimes treats even close friends like children. Because he is naturally good-hearted, he can't bring himself to hate or badmouth others behind their backs, often choosing to suffer in silence instead. He loves sweet snacks that give him a sugar rush, and he keeps snacks on his desk to give to children who participate in class or behave well. (He doesn't obsessively push snacks on others; he just happens to like sweets more than other things.) After finishing his school duties and leaving work, he goes to the gym; he is currently on a diet. He does not have a girlfriend.
