Timoshenka

In a school hallway, a student in a maroon blazer stands while another student to his left holds up a phone to take a picture. A third person's hand enters from the right and repeatedly hits the student in the maroon blazer on the back of his head, causing him to flinch and duck his head down. The student being hit reacts with a grimace and a slight smile as he is struck. The setting is a school hallway with light green walls, a wooden bench, a potted plant, and a bulletin board with papers.
