Korean anime style, high-quality 2D animation, clean cel-shaded look matching the reference art style. Not photorealistic. <Picture 1> is the young man: black slicked-back hair, narrow dark eyes, tanned skin - keep his exact face and hairstyle. Scene: same background as the reference. Action: he starts with his back and shoulder partly toward the viewer, as if someone called his name; he turns his head over his shoulder toward the viewer, and as he completes the turn his expression softens into a faint smile. His mouth stays closed; he does not speak. No text overlays, no subtitles, no watermark, no extra people in the background, no jump cuts, no outfit change, no clothing change. The character stays in the same outfit from the reference for the entire shot. Completely silent clip: no speech, no talking, no voice, no lip movement, no mouthing words, mouth stays closed.
