Brother. 💙

A young man with dark hair and a blue shirt lies on a tiled floor, then looks up with a determined expression, his blue eyes shown in close-up, before the scene cuts to another young man with glasses and a school uniform looking through a doorway, followed by a close-up of his face, and finally back to the first man with a shocked expression as he grips a knife. The setting appears to be an indoor space with wooden door frames and tiled flooring.
