an ORDINARY Korean man in his mid sixties — explicitly NOT a fashion model, NOT idealised, NOT a beauty-standard face. A real individual Korean face: slightly asymmetric features, visible skin texture and pores, a facial structure that is clearly distinct from other people. He runs a small calligraphy academy. He looks approachable and well-groomed, but ordinary. Full white hair combed back, round thin-rimmed glasses, a soft grey traditional-cut linen jacket with a mandarin collar. Warm indoor light bouncing off pale hanji paper surfaces, soft and low-contrast; the blurred background is a calligraphy studio interior, heavily out of focus. Warm, crinkled eyes, a slow closed-mouth smile. Square 1:1 social-media profile photo, photorealistic candid portrait photograph. FRAMING (strict): the crop ends at the middle of the chest — nothing below the chest is in frame. The head, the neck and BOTH shoulders are all fully inside the frame, with a small margin of empty space above the hair. The subject fills most of the frame and is centred. The background is visible but softly out of focus. Normal healthy human anatomy: head, neck and shoulders all clearly present and correctly proportioned. NORMAL neck proportions, not elongated. Two normal hands are NOT required in frame; no extra limbs, no distorted fingers. The background is blurred beyond legibility — absolutely NO readable characters, NO calligraphy strokes forming letters, NO hanging scrolls with writing. No text, no letters, no numbers, no signage, no logo and no watermark anywhere in the image. Do NOT include any real company logo, real brand name or real trademark.
