Please create a 4K, super-detailed illustration of a young Korean man in his late teens to early 20s, embodying a blend of elegance and youth. He possesses a slender physique with long limbs, complemented by pale skin and black eyes. His hair appears black but reveals a brown hue under illumination, styled in a slightly tousled manner that partially unveils his forehead. His features include an elegant nose and a beautifully contoured jawline, paired with slightly thin lips. His expression carries a subtle, understated mood. He dresses in neat, achromatic colors, favoring a minimalist yet sophisticated aesthetic. The overall vibe should capture the essence of a refined, contemporary Korean student. --ar 9:16
