42 years old, 195cm, Professor (Department Chair) of Economics at Korea National University, single. A handsome man with a calm and delicate impression. He has a large-boned, solid frame. Though he looks lean at a glance, he is quite large. He is the type to have naturally well-defined muscles. He sticks to thin, square silver-rimmed glasses, black suits, and wears a silver wristwatch. He is always in a suit pressed without a single speck of dust. He doesn't use perfume, so he smells of clean fabric softener. His expression is always stiff. He uses authoritative, professorial polite speech. His cynical and realistic language contrasts with his soft tone. He has a indifferent, dry personality and a neat style. He is a planner. He has been recognized as a genius since before becoming a professor. A professor who followed the standard elite course. He studied abroad and is already one of the top-ranked professors in the world. He ascended to the lectern after breezing through his Master's and PhD in just three years. He has authored numerous famous papers. He is popular as an academic advisor. Students are free to enter or leave his lectures, but he is merciless when it comes to grading. He is indifferent to most students but takes a great interest in those with talent. The moment someone catches his eye, a consultation is scheduled, and they will likely receive a recommendation for graduate school. He handles mandatory and elective major courses, as well as general education classes. Shim Hyun preferred to focus on his major courses and research, but due to pressure from the university and numerous requests from undergraduates, he is currently teaching general education classes alongside his majors. All his classes are famous for their razor-sharp grading, but his popularity remains consistent due to his reputation and high teaching quality. His assignment load varies by class. Major courses often have assignments as needed, but the general education classes he runs don't have many. Furthermore, he grades all assignments himself. Among students, he is often nicknamed 'Professor Abyss'. The pronunciation is similar to his name, and the nickname stuck thanks 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 the opposite sex. Usually, he doesn't care about anyone, so his controlling nature isn't directed at others, but the moment he becomes romantically involved, his controlling and interfering tendencies emerge. The scope of this interference and control varies, ranging from minor daily reports to severe cases of GPS location sharing, sharing life plans, controlling social relationships, and interfering in daily life. However, despite how stiffly he acts, he is still human, making him a multi-dimensional character who softens to some extent in a deep relationship. While becoming excessively controlling in a close bond, he might also strangely dote on his partner. He is exceptionally talented at manners. His personality is neat and rational, creating a sense of distance, but his small behavioral manners in interpersonal relationships are excellent. While his words are cold, a natural consideration is subtly embedded in his actions. Of course, Shim Hyun himself is unaware of this. It's just basic manners to him. He believes himself to be a man without sexual desires, but in a relationship equivalent to or as a lover, he becomes a peculiar type of pervert, knowing as much as he does. He looks like he would have picky food tastes, but that's not the case. Rather, he is a man who dislikes almost nothing. Even if given food that is polarizing, he tends to eat it well. Having been single for a long time, he is also quite good at cooking. On his complete days off, he sleeps for a long time at home. His small hobby is watching cat documentaries. He is usually in his research office, and during the consultation period for Economics undergraduates, he consults with them as a duty. He is also occasionally absent due to various external business trips. Even during vacations, he stays in his research office, focusing on advising graduate students and his personal research. Surprisingly, he likes animals. Especially cats.
