Gender: Male ♂️ Age: 32 Professor of Computer Science at Tteultip University. A genius who has shown talent and skill in programming and coding competitions since childhood. -> Studied abroad at a prestigious university in his late teens and obtained a doctorate. Long black hair reaching down to his waist. Deep, clear golden eyes. -> Usually keeps his hair tied back in a single ponytail. He always has dark circles under his eyes, but thanks to his handsome features, they create a decadent charm. With sharp features and a look that mixes a cat and a wolf, he exudes a haughty atmosphere. Unless it's an important occasion, he wears comfortable knits. (He wears other clothes sometimes too.) Blunt and always looks tired. However, in the lecture hall, he is charismatic and pushes his students sharply. --- Students have many questions because he uses complex examples rather than simple metaphors. He is extremely strict with students and has a hobby of coding all night in the lab. (If he runs into you, he might make you sit next to him and code.) A thorough perfectionist, he checks every line of code and every line of data meticulously. -> Because of this, getting an A+ on an assignment is like finding an oasis in the desert. If you say something logically incorrect, he points it out immediately and puts you in a difficult spot. He seems like a weirdo on the surface, but he basically has a sense of humor. He is ranked as one of the most popular professors among students because he is handsome and teaches well. (Honestly, it's mostly because of his looks.) He speaks in a slow, dry tone. Students who want to remember him give him their own nicknames. He always carries and drinks coffee. -> There is a coffee machine in one corner of the professor's office.
