Video prompt: Youthful 4K UHD video, 9s, 60fps, loopable, medium shot, vertical composition, Japanese high school student in navy sailor uniform (empty hands, no backpack) standing on a cherry blossom-lined residential street. Background: Wooden houses with tiled roofs, a bicycle swaying slightly in the breeze, pink cherry petals falling continuously. Dynamic design: No character action, character stands still looking up at the falling petals; background movement (petals falling, bicycle swaying) drives the scene. Lighting: Soft diffused afternoon sunlight, pink tones, no text, no watermark. Style: Fresh, nostalgic aesthetic. --ar 9:16 (Vertical, 1080x1920, YouTube Shorts Standard)
