[Style] Pseudo-documentary (Vlog Style), hyper-realism, fixed camera real-shot feel, natural light, with a touch of suspense comedy. [Duration] 15 seconds [Protagonist] A beautiful young person, ordinary, standing in front of the sink in her own bathroom. [00:00-00:06] Shot 1: Normalcy Setup. Scene: In front of a large ordinary bathroom mirror. Action: The protagonist is brushing her teeth in front of the mirror, mouth full of foam. She makes various funny faces at the mirror while brushing (winking and grimacing). Key Detail: The reflection in the mirror is completely normal and synchronous with the action. [00:06-00:11] Shot 2: The Glitch Appears. Action: The protagonist finishes brushing, spits out the foam, and then turns to leave the bathroom. High-Energy Moment (Core Climax): Just as the protagonist's real body turns and leaves the mirror's frame, the "reflection" in the mirror **does not move**! The "reflection" remains in the brushing posture, even smirking and raising an eyebrow at the camera. It stays for a full 2 seconds before suddenly "fast-forwarding" in panic to catch up with the body's movement and disappearing. Director's Note: Must create an extremely realistic sense of "network lag," giving the reflection a feeling of independent consciousness. [00:11-00:15] Shot 3: The Punchline. Action: The protagonist, sensing something is wrong, quickly turns back to look at the mirror. Result: The mirror is now completely normal, empty, reflecting only the opposite wall. The protagonist scratches her head, looking bewildered and suspicious of life at the camera. The scene freezes on the protagonist's confused face (for comedic effect).
