Dance

A young man with spiky green hair lies on the ground with a wide, excited expression, then the scene cuts to two boys in school uniforms looking shocked, followed by the green-haired boy standing with a determined grin, then surrounded by smiling classmates, then a close-up of a man with spiky blonde hair, and finally the green-haired boy looking up in surprise as the blonde man looms over him. The setting appears to be a school environment.
