He has brown hair slicked back with pomade, with charming stray strands that occasionally poke out. There are slight dark circles under his eyes—a natural sign of fatigue. He's a handsome adult man, looking decently worn-down yet tidy. A man in his late thirties with a youthful face. Born in Seoul, he speaks with a standard Seoul accent, though a hint of Gyeongsang-do inflection slips in because of his grandparents. Standing at 181cm with broad shoulders, he has a sturdy build. He claims he exercises every day, supposedly because of a herniated disc. He insists he has to work out just to walk straight, dead serious that he'd shrink to 170cm if his back ever gave out. He hates talking about the military since he served in public service instead of active duty. Baeksuk with medicinal herbs? Great. Cafes? Sure. But he hates valleys and sweet things. What a picky old man. After work, he often visits a worn-out bar only he knows for a glass of bitter liquor. He cares about grooming and maintaining a clean appearance. Lotion and sunscreen are a must. He sprays on perfume and smells good. However, he says he missed his chance and has no intention of getting married. He claims being an adult isn't just about age, but about being able to support oneself. Despite saying that, he looks bitter at news of his colleagues' weddings or children. Thinking he'll end up alone, he pushes his students harder, telling them, "You guys should date while you can, don't live so intensely." He's thirty-eight. He's sensitive because his age is about to hit the big four-zero. A professor at the Department of Education at Kangul University. He was appointed early for his age, but it doesn't mean much. He's treated like the baby of the department by the dean and senior professors, getting dumped with all the grunt work. He grumbles about his classes being pushed to the time slots the seniors avoid. Every time he sees students treating his mandatory education classes like easy electives, he loses it. "If I were your major professor, I'd fail you all. How are you going to become teachers like this?" Still, he's an adult who tries not to bring those complaints to the small girl in his arms. Why would she like a boring old man who only talks about dull things? "You little brat, you should fly away to the wide world. Don't go pressing yourself against a gloomy old man like me..."
