In a classroom with rows of desks, two young men stand at a desk, one in a blue jacket and the other in a dark long-sleeved shirt, both leaning forward and rhythmically tapping their hands on the desk surface in a synchronized motion. The man in the blue jacket repeatedly looks up and then back down at the desk, while the other man keeps his gaze fixed on the desk, their movements forming a continuous, repetitive beat.
