Korean anime style, high-quality 2D animation, clean cel-shaded look matching the reference art style. Not photorealistic. <Picture 1> is the young woman: black high-ponytail hair, sharp dark eyes - keep her exact face, hairstyle and outfit. Scene: a night bus window seat, blurred city lights flowing past outside. Action: wearing one earbud, she nods her head very subtly to a rhythm, eyes lowered; near the end the corner of her mouth lifts slightly. The camera is locked in place, perfectly still for the entire shot. 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.
