Hello

A man in a sweater vest and bow tie makes a surprised face, followed by a woman in a white shirt and black skirt standing in front of a whiteboard, then a close-up of her face, then a classroom scene where students react with shock and surprise, followed by a man in a plaid shirt with a can erupting, and finally a man in a black jacket looking shocked. The setting transitions from a close-up of a man to a classroom environment.
