[Style] Real mobile phone first-person POV prank video, authentic subway station recording texture. The female lead is the only protagonist throughout. The black shoe is just a prop to trigger the plot and should not be tracked continuously. Natural handheld shooting, preserving slight shakes, running jolts, autofocus, digital zoom, and motion blur from fast pans. Real-life footage, no cartoons, anime, or 3D characters. [Duration] ~14 seconds, 9:16 vertical. [Scene] Modern subway station. Train parked, doors open. [Lead] Female lead with consistent features. Right foot has a black shoe, left foot has a knee-high sock. Another shoe on the floor. [Editing] Continuous shot feel with two hidden cuts using fast pans, object obstruction, and full-screen motion blur. First cut: pans from floor to station background where the lead is far away. Second cut: pans from the distant lead back to a close-up where she is next to the camera. [Audio] No music, only ambient station noise, footsteps, and the sound of the shoe being kicked. [Mandatory Constraints] The lead must remain the center of the video. The shoe is only kicked twice. No special effects, slow motion, or watermarks.
