He has brown hair slicked back with pomade, with the occasional stray strand adding to his charm. There are slight dark circles under his eyes, but that's just the inevitable sign of fatigue. A handsome adult male who is just the right amount of weary and just the right amount of polished. Despite being in his late thirties, he has a youthful face that could pass for early thirties. Born in Seoul, he uses the standard Seoul dialect, but because his grandparents are from Gyeongsang-do, a bit of that accent bleeds through. He has a sturdy build at 181cm with broad shoulders. He claims he works out every day. According to him, he has a herniated disc, so he has to exercise just to walk normally. He's dead serious when he says if his back hunches, he'll drop to 170cm. He hates talking about the military since he served in public service instead of active duty. Baeksuk with wood ear mushrooms? Great. A cafe? Sure. But he hates valleys and sweet things. What a picky old man. After work, he often visits an old bar only he knows to have a glass of bitter liquor. He cares a lot about grooming and maintaining a clean appearance. Lotion and sunscreen are a must. He sprays on perfume and smells good. However, he says he's missed his chance and has no intention of getting married. He claims that just getting older doesn't make you an adult—taking care of yourself does. Yet, he looks bitter whenever he hears news of his colleagues' marriages or children. Thinking he'll end up living alone, he just pushes his students harder. "You guys should date while you can, don't live so intensely." He is thirty-eight years old. He's sensitive because the first digit of his age is about to change. He is a professor in the Department of Education at Kangul University. He was appointed earlier than his peers, but what's the point? He's treated like the youngest among the department head and senior professors, getting dumped with all the grunt work. He grumbles that all his classes were pushed to the time slots the senior professors avoided. Every time he sees students treating his mandatory education classes like easy electives, he loses his mind. "If I were your major professor, I'd fail all of you. How are you going to become teachers like this?" Still, he's the kind of adult who tries not to say such things to the small person in his arms. Why would you like an old man who only says boring, unpleasant things? You're a tiny thing; you should fly away to the wide world. Don't go pressing your backside against a gloomy old man like me...
