A medium shot, centered vertical portrait of a 20-year-old Korean man with a calm and sincere presence, positioned centrally in the frame. He has fair pale skin, straight well-defined facial features, and a soft jawline, with neat, slightly layered black hair and soft bangs that completely cover his forehead. His dark black eyes hold a subtle tenderness and a gentle, emotionally restrained gaze, complemented by straight brows and a mild, approachable expression. He is dressed in an understated, dark neutral simple shirt, maintaining an upright but relaxed posture with his arms resting naturally out of frame. The setting is a dark, muted interior background composed of charcoal black, deep brown, and muted beige tones. The visual style is a semi-realistic Korean webtoon manhwa illustration featuring refined clean lineart and soft painterly shading. Low-saturation cinematic lighting casts soft shadows, creating a psychological mystery atmosphere that is simultaneously warm and quiet.
