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 hair in low twin-tails, amber droopy eyes - keep her exact face and hairstyle. <Picture 2> is the young man: black slicked-back hair, narrow dark eyes, tanned skin - keep his exact face and hairstyle. They are two different people; do not mix or blend their facial features. Scene: a dark backyard at night; each holds a lit sparkler between them. Action: sparks crackle from both sparklers; she waves hers in a slow small circle, mesmerized; he watches her face instead of the sparkler, smiling quietly. 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. Both characters stay in the same outfits from the references for the entire shot.
