A young man with black hair and a dark suit leans forward with a determined expression, then straightens up and walks away from a doorway into a room with clothing racks. The scene cuts to a young man with red hair and blue eyes looking up with a surprised expression, then to a group of three students—two boys and a girl—standing in a classroom or office, where the red-haired boy looks up with a surprised expression while the other two watch him.
