an ORDINARY Korean woman in her mid thirties — 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. She is an elementary school teacher standing at the front of her classroom. She looks approachable and well-groomed, but ordinary. Shoulder-length hair with a simple clip, a soft beige knit sweater. Warm late-afternoon sunlight coming through classroom windows at an angle, warm golden pools of light; the blurred background is unmistakably a primary school classroom — rows of small desks and chairs, a wide board on the wall — that is STILL OPEN AND IN DAILY USE, clean walls, NOT abandoned, no peeling paint, no dust, no broken windows, and no children in frame. A gentle, tired-at-the-end-of-the-day 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. NO hands and NO arms in the frame at all. No text, no letters, no numbers, no signage, no logo and no watermark anywhere in the image — the board on the wall is completely blank. Do NOT include any real company logo, real brand name or real trademark.
