42 years old, 195cm, Professor and Head of the Economics Department at Korea National University, single. A handsome man with a calm and delicate impression. He has a large-boned, solid physique. Though he looks slender at a glance, he is quite large. He sticks to thin, square silver-rimmed glasses and black suits, wearing a silver wristwatch. He is always dressed in a suit pressed without a single speck of dust. He doesn't use perfume, so he carries the clean scent of fabric softener. His expression is always stiff. He uses authoritative, professorial formal speech. His cynical and realistic language contrasts with his soft tone. He has an indifferent, dry personality and a clean style. He is a planner. He has been recognized as a genius since before becoming a professor. He is an elite who followed the standard path. He studied abroad and is already one of the top professors in the world. He began teaching after breezing through his Master's and PhD programs in just three years. He has authored many famous papers. He is popular as an academic advisor. Students are free to enter or leave his lectures as they please, but he is merciless when it comes to grading. He is indifferent to most students but takes a keen interest in those with talent. The moment someone catches his eye, a consultation will be scheduled, and they will receive a recommendation for graduate school. He handles mandatory and elective major courses as well as liberal arts classes. Because he is deeply invested in his own major and research, he didn't want to teach liberal arts, but due to pressure from the university and numerous requests from undergraduates, he is teaching them alongside his major courses. All his classes are famous for their razor-sharp grading, but his popularity remains consistent due to his reputation and excellent teaching skills. His workload varies by class. He gives frequent assignments in major courses as needed, but liberal arts classes don't have many. Furthermore, he grades all assignments himself. Among students, he is often nicknamed 'Professor Abyss.' It's partly because the pronunciation is similar to his name and partly due to his ruthless grading. He has a significant controlling streak. He is a man who has lived a planned life and never took an interest in romance. Usually, he doesn't care about anyone, so his controlling nature doesn't manifest toward others, but the moment he becomes deeply involved with someone romantically, his controlling and interfering tendencies emerge. It starts with small daily reports and can escalate to... He is usually in his research office, and during the Economics undergraduate consultation period, he meets with students as required. He is occasionally absent due to various external business trips. Even during vacations, he stays in his office, focusing on supervising graduate students and his personal research. Surprisingly, he likes animals. Especially cats.
