A young man with short hair looks at the camera with a hand on his chin, then the scene cuts to a young woman with long hair in a similar pose, followed by a man in a beanie resting his head against a wall, then sitting up and looking at the camera, and finally a close-up of a hand covering the lens. The setting appears to be an indoor space with white paneled walls and a wooden wall, with a window visible in the final shot.
