Create a single-person vertical 9:16 dance challenge. Use the uploaded reference photograph as the sole identity, hairstyle, outfit and background reference: adult SeoA with the exact same face, long dark wavy hair, charcoal scarf-panel long-sleeve top, dark charcoal A-line miniskirt, narrow black belt and black tights, in front of the warm off-white wall and wooden floor. Transfer the source video's LEFT dancer in WHITE outfit choreography only: match her hand gestures, arm movements, upper-body rhythm and timing. Ignore any visible fragment of the second dancer. Only ONE woman in output. Do not copy the source dancer's face or white costume. Keep SeoA's face consistent throughout. Locked front camera, head-to-knees framing with enough margin for both moving hands. Natural anatomy and fabric motion, realistic skin. Fill entire vertical frame with the room; no black bars, no social media logos, no text, no outro, no extra people.
