Craziness

Students in white uniforms sit at desks in a classroom, writing on papers, while a male student in a white shirt sits alone at a desk by a large window, looking out at a cityscape. The scene cuts to a close-up of a male student with black hair and a slight smile, then to a female student with brown hair and glasses smiling, followed by a male student in a blue shirt with a pained expression, raising his arm as if in distress.
