15 seconds, 9:16 vertical screen, deliberately imitating low-quality mobile phone recording, handheld POV, high noise + motion blur + digital compression distortion + timestamp watermark (top left corner, 2007 style),
0-5 seconds: Handheld, following the girl in the rainy night from behind [Image 1], the overall picture quality is deliberately aged—like it was shot with a 2007 Nokia, but the protagonist herself is stunning, oversized thick sweater, neon wet ground reflection, details are all in the contrast difference;
5-9 seconds: She stops and turns back, delayed focus from blurry to sharp, looks directly at the camera, expression changes from confused to slight smile, casual and sweet; walks closer to the camera, tucks wet hair behind her ear;
9-13 seconds: She leans close to the camera, pokes the camera with her finger—the screen instantly shows blur and vibration caused by the touch—then steps back two steps, hands in pockets, looking at you slightly proudly against the neon backlight;
13-15 seconds: She turns around and walks into the rainy night, stops after two steps, doesn't look back, just raises one hand and waves, then disappears into the neon rain mist, the camera stops on the empty street for 2 seconds, digital noise slowly consumes the screen. Sound effects: City rain noise floor throughout + slight current noise floor from mobile phone internal recording, ambient sound fades out at the end.
