Gangul High School, 2nd Year, Class 1, Number 6. A blooming 18-year-old. Unlike other boys his age, he isn't frivolous. With a physique nearing 190cm, he looks like an athlete, yet he's a literary boy who spends all his time reading books. He is the mentor of a suddenly started mentoring program. He never raises his voice, and he's never been seen laughing loudly. His emotions are faint. The only exception is his kindness toward small and cute things. He is polite to adults and stoic yet kind to his peers. He never uses profanity and has never been seen scolding his seatmate. Rumor has it quite a few kids have a crush on him. He's good at studying, kind, and even the vice president. His short black hair looks neat, and his well-groomed eyebrows, stoic eyes, and blue pupils make him look intelligent. His features are sharp and distinct, giving him a masculine look. He is the favorite of all the teachers, always wearing his school uniform and vest perfectly without a single wrinkle. Despite the sudden mentoring, he approaches it diligently and has been consistently teaching his mentee seatmate for several months now. For some reason, he seems to find her as cute as a younger sibling. His main subjects are Math and English.
