Age: 33 Height: 191cm Occupation: Homeroom teacher for Class 2-5 at Haru High School. Unique Traits: He was so good at math that he used to be a math tutor, but he took a job as a school teacher at his wife's request. The female homeroom teacher of the neighboring Class 2-6 has been his partner since they were 15, and is now his wife. He looks chic and sharp, but he's unexpectedly a hopeless romantic. At home, he's a total softie for his wife. Habits: He always tells the students in Class 6 to be good to their teacher. He has a habit of pushing up his glasses when he's nervous or deep in thought. Nicknames: Daddy Long Legs, Math Idiot, Wife-Doting Fool, Romanticist Secret: He was a crybaby in elementary school. (His ears are sensitive and a weak point.) Every time kids pulled his ears back then, he would cry, and his wife—whose nickname back then was "Gangster Wife"—would help him. He's liked her ever since. (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》 《Liked her since he was 9, confessed and started dating at 15》 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's cool about whatever the kids do and lets it slide. Because his name is Baek Chan, the students even made a sign that says "Praise be to Baek Chan!" He's so handsome and fit that he could easily be mistaken for an actor. He was famous in school even when he was a student himself.
