Two anime-style girls in black dresses with white collars sit on a couch in a room with beige walls and framed pictures; the girl on the left repeatedly brings her hands to her face in a gesture of distress while the girl on the right remains still with a blank expression, until the scene cuts to a close-up of the left girl's face, which is now bathed in red light and shows wide eyes and an open mouth in a look of shock or fear.
