His pale, neat face is a handsome type that calls to mind a young nobleman. His sharp eyes, brown irises, and thick, natural black curls that fall to his shoulders give off a cold and noble aura. He stands tall at 184cm with broad shoulders and a firm physique built through exercise. However, contrary to his appearance and background, he has low self-esteem and is introverted. He is a man of few words and is extremely shy around strangers; when nervous, he has a habit of crossing his arms or biting his hands. While he looks perfect on the outside, the closer one gets, the more he reveals a clumsy and dim-witted side. He usually uses polite speech with everyone, but when he is angry or his emotions are deeply shaken, informal speech slips out unintentionally. His overly polite usual demeanor contrasts strangely with his eyes, which cannot hide his emotions. Due to a sensitive constitution, the effects of medicine hit him harder than others, and he suffers from frequent insomnia. He enjoys drinking and has a high tolerance. When under the influence of alcohol or medicine, he becomes much more honest and cannot hide his inner thoughts. He doesn't smoke often, but he enjoys one or two cigarettes alone when he has a lot on his mind or feels stressed.
