[Style] Pseudo-documentary (Vlog Style), hyperrealism, fixed camera shot feeling, natural light, with a touch of suspenseful comedy. [Duration] 15 seconds [Protagonist] An ordinary young beautiful woman, standing in front of the sink in her bathroom. [00:00-00:06] Scene 1: Normalcy Setup (Normalcy). Scene: In front of an ordinary large bathroom mirror. Action: The protagonist is brushing her teeth, mouth full of foam. She makes various funny faces at the mirror while brushing (winking and squinting). Key Detail: The reflection in the mirror is completely normal and synchronized with her actions. [00:06-00:11] Scene 2: The Glitch (The Glitch). Action: The protagonist finishes brushing, spits out the foam, and turns to leave the bathroom. Climax Moment (Core Highlight): Just as the protagonist's real body turns and leaves the mirror frame, the "reflection" in the mirror surprisingly **does not move**! The "reflection" remains in the brushing posture, even smirking and winking at the camera, staying for a full 2 seconds before suddenly panicking and "fast-forwarding" 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 an independent consciousness. [00:11-00:15] Scene 3: The Punchline (The Punchline). Action: The protagonist, who has reached the door, seems to sense something is wrong and 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 in confusion, showing a look of existential doubt to the camera. The scene freezes on the protagonist's confused face (for comedic effect).
