Korean 2D cel-shaded anime style, clean line art, flat shading with soft cel shadows, no photorealistic rendering. The scene features a single adult woman in her 20s, seen from behind in a 3/4 rear angle, waist and hips filling the frame. She keeps the exact face and hairstyle from : shoulder-length naturally wavy hair with bangs. She is dressed in a short cream-colored cropped t-shirt, white cotton panties, and white over-knee socks. The outfit is newly designed for this shot and is not taken from the reference. Interior, simple bedroom background: a plain light-beige wall with the edge of a bed barely visible at the bottom. Minimal composition. Camera is fixed and static, centered on the woman who stands with her back to the camera. Timed action over the full 5-second clip: - 0.0-1.0s: She stands with her back to the camera, both hands touching the waistband of her panties at her hips. - 1.0-2.5s: Both hands grip the waistband and slowly begin pulling the panties down; the fabric slides down past the top of her hips. - 2.5-4.0s: The panties slide down along the curve of her hips down to just above the knees, fully exposing her buttocks. - 4.0-5.0s: The panties stop below the knees and remain there; her buttocks stay fully exposed as the clip ends. No dialogue. No sound effects, no music, no voice. Her lips stay closed and still throughout. No text overlays, no subtitles, no watermark, no extra people in the background, no camera movement, no zoom, no panning, no jump cuts, no additional actions beyond the disrobing motion, no photorealistic or 3D rendering, no non-cel-shaded style, no outfit change, no clothing change, no wardrobe change.
