10-second short video, 9:16 vertical, 4K HD, 60fps, smooth and silky. Driven by strong-beat DJ dance music BGM for beat-sync, actions switch seamlessly with the drum beat. Fixed overhead angle of about 40 degrees from the front-top throughout, pure white wall background. Character: strictly refer to the attached image, keep exactly consistent. Overall image is youthful, playful, full of vitality, ultra-realistic style, absolutely avoid cartoonish, CG feeling, over-smoothing.

Core actions and expressions · beat-sync rhythm (10 seconds): the girl stands at the center throughout, facing the high-angle camera.

All actions and expressions strictly switch on the BGM accents. 0.0-0.8s | Side entrance, surprised and lively: lightly enters from right side of frame — hands behind back, body in a diagonal pose, peeking out like playing hide-and-seek.

Head slightly down, eyes look down, expression becomes shy — smile widens, apple cheeks puff up, eyelashes cast shadows on cheeks. As if suddenly embarrassed after turning. 3.2-3.7s | Arms out bloom, sweet smile: on the beat — body stands straight, hands gracefully extend from hips to sides.
