[Generation Goal]
The tempo is light and fast, with a repetitive rhythm. Not an advertisement or a cinematic video, but looking like a live-action clip a friend took on their smartphone on the spot.

[Stage 1 | 0-5 seconds]
Initial state: The fixed frame shows only a sunlit wooden wall. Main event: <Model A> enters quickly from the right edge, stops in the center, twists her waist once to flip her pleated skirt and let it settle, faces the lens directly as her closed mouth relaxes into a smile with narrowed eyes. She then walks out from the left edge. End state: The frame is empty again, with the right edge open.

[Stage 2 | 5-10 seconds]
Continuation from previous: The camera hasn't moved, framing is identical. Main event: <Model B> enters from the right edge, stops in the center with her back to the lens, showing the cardigan draped over her shoulders and the tiered hem of her dress, then turns her face over her shoulder toward the camera. Her expression is quiet and expressionless, with lips slightly parted. She turns her body fully back toward the lens and walks out from the left edge. End state: The frame is empty again, with the right edge open.

[Stage 3 | 10-15 seconds]
Continuation from previous: The camera hasn't moved, framing is identical. Main event: <Model C> enters from the right edge, stops in the center, rotates her upper body once to the right to show the silhouette of her knit vest and wide linen pants, then takes one step closer to the lens to bring her face near, laughs out loud while raising her shoulders, resulting in a frame that fits from her thighs up. She never gets closer than about 1 meter from the lens. She returns to the center position, stands up straight, and remains there with a smile. End state: <Model C> stands facing the camera in the center, and the handheld frame settles and stops on her.
