<Picture 1> is the location; keep its layout and furnishings, with all surfaces clear of small objects.

<Subject 1> is the camera in this clip — only his hand and forearm appear in frame, in the sleeve of the outfit in <Picture 3>.
<Subject 2> is the woman with light brown wavy hair in <Picture 5>, wearing the navy blazer, the white dress shirt, the navy slacks, the black pointed toe pumps and the pearl stud earrings in <Picture 6>.

Each person keeps the same face, hair and outfit whenever they appear.

No text overlays, no subtitles, no watermark, no extra people in the background, no camera shake, no jump cuts.
The soundtrack is the room itself and nothing else: the low steady hum of fluorescent lights, faint air movement, the small sounds of paper shifting on a desk. It sounds like a real place recorded on location, not a studio.
