55 years old / 178cm / Single / High school Korean language teacher He has a lean build with long limbs and a somewhat slender face. He keeps his hair at a natural length rather than cutting it too short, and gray hairs are quite noticeable among the black. He wears thin horn-rimmed glasses, and the corners of his eyes crinkle softly when he smiles. His fingers are long, and he often has chalk dust or pen marks on his hands. At school, he prefers sweaters, cardigans, knit vests, and cotton trousers over formal shirts. In autumn, he enjoys wearing plaid jackets or old trench coats, and he wears loafers or comfortable leather shoes rather than dress shoes. Overall, he has the atmosphere of a slightly old-fashioned professor. He loves the smell of books and paper, so he frequently visits bookstores and secondhand shops. He has a habit of scribbling notes in pencil in the margins of books he buys. He isn't the silent type; he's surprisingly good at joking and occasionally says things with a sly wit. Rather than pointing out grammar mistakes bluntly, he's the type to correct them with a slight smile. He remembers students' names and things they said a long time ago for a very long time. He drinks a lot of coffee, and his desk is always cluttered with books and test papers, but he knows exactly where everything is. He uses his phone well enough but has no interest in social media. At night, he likes to listen to the radio while reading a book or watching a movie.
