Off to work...

A man in a light-colored shirt sits at a wooden desk, resting his head on his hand while looking down at papers, then looks up and to the side; the scene cuts to a man in a blue tracksuit sitting at a desk, then to a woman with red hair looking to the side, and finally to a man in a light purple shirt sitting at a desk with a chalkboard behind him. The setting is a classroom with light-colored walls, desks, chairs, and a window.
