Older brother

A young man with black hair and a blue jacket stands in a locker room, facing a silver-haired man in a grey tracksuit who makes a peace sign; the scene cuts to a close-up of the black-haired man's wide, sweating eyes, then to the silver-haired man in a suit looking serious, followed by him adjusting his hair, and finally to the black-haired man screaming in distress while the silver-haired man turns away. The setting is a school or sports facility locker room with blue benches and lockers.
