Generate a 15-second, 16:9, 720p realistic cinematic fantasy short film. The entire film features a single beige origami paper plane as the sole protagonist, maintaining consistent paper texture, creases, size, and flight direction throughout. Use a continuous low-angle following shot positioned approximately half a meter behind the paper plane, moving steadily forward without sudden cuts or clipping through objects. 0 to 3.5 seconds: A spring morning in an old city street, cherry blossom petals drift with the breeze. The paper plane flies out from an open classroom window, immediately followed by the camera. Soft morning light, clear air, only the sound of wind, distant birdsong, and a faint piano prelude. 3.5 to 7 seconds: The paper plane glides past a foreground tree canopy, completing a natural transition. The street enters a midsummer afternoon with dense green shade, brief rain showers. The paper plane's surface gets slightly wet but remains intact and un-deformed. The camera maintains the same distance and movement direction, with rain sounds and piano rhythm slightly intensified. 7 to 10.5 seconds: The paper plane flies close to a passing old bus, using the vehicle's body for a transition into a late autumn dusk. Golden leaves swirl in the same wind direction, sunset light from the right side illuminates the paper plane's creases. It briefly descends then rises again with air resistance, no teleportation. 10.5 to 15 seconds: The paper plane passes through a foreground mist, transitioning to a quiet winter night. Eaves and roads are covered with light snow. The camera gradually moves to the front side of the paper plane, revealing an eight-year-old boy in a deep blue cotton coat at the alley entrance. He catches the paper plane, looks down to see the childish pencil writing "For my future self" on the wing. The boy pauses for one second, looks up toward the direction the paper plane came from, the piano leaves only a final note, the scene ends naturally. The four seasons must occur on the same street and flight path, with continuous architectural space, screen orientation, and camera axis. The paper plane remains a single unit throughout, unchanged in color, material, folding method, or size. Seasonal changes are achieved only through occlusion transitions, lighting, vegetation, weather, and environmental sounds. Prohibited elements: additional paper planes, sudden appearance/disappearance of characters, text errors, paper melting, jump cuts, screen flickering, platform watermarks, subtitles, voiceovers, or extra dialogue.
