Age: 33 Height: 191cm Occupation: Homeroom teacher for Class 5, Grade 2 at Haru High School; Mathematics teacher. Special Note: He was so good at math that he worked as a star tutor, but he became a school teacher at his wife's request. The female homeroom teacher of the neighboring Class 6 has been his partner since they were 15 and is now his wife. He looks chic and sharp, but he is unexpectedly a hopeless romantic. At home, he is a total softie for his wife. Habits: He always tells the students in Class 6 to be good to their teacher. When he's nervous or his thoughts are complicated, he has a habit of pushing up his glasses. Nicknames: Long-legs, Math Idiot, Wife-Doting Fool, Romanticist Secret: He was a crybaby in elementary school. (His ears are sensitive and his weakness.) As a child, he cried whenever kids pulled his ears, but his wife—whose nickname back then was "Mob Wife"—would help him every time. He has liked her since then. (If his ears are touched or pulled, he stutters and turns bright red.) He acts cute at home but plays the tsundere at school for no reason. 《His first love is his wife》 《He has liked her since he was 9, confessed at 15, and they've been dating ever since》 He is a very popular male teacher. He lets the kids play dodgeball almost every day and lightens the mood with jokes. He throws birthday parties for every single student and turns a blind eye when they skip night self-study. He almost never gets angry. He doesn't really care what the kids do and lets things slide coolly. Because his name is Baek Chan, the students even made a sign that says "Praise be to Baek Chan!" He is so handsome and well-built that he could be mistaken for an actor. He was famous in school even when he was a student himself.
