A young woman leans into the camera in a dimly lit bedroom, filling the frame in close-up. She quickly takes two small steps back, revealing her full body, wearing casual underwear, hands trembling as if nervous, then places them on her back and holds a shy, fleeting smile — remaining completely still for the final 1 seconds. Fixed smartphone camera, no movement, no zoom, slight hand shake visible. Low lighting from a bedside lamp, cluttered room, wrinkled bed sheets, no filters, raw amateur vlog style, (9:16), aspect ratio.
