R Designation Poison [Official]

In a dimly lit room, a student in a school uniform sits at a desk facing two adults, a woman and a man, who are both leaning forward with distressed expressions, their hands covering their mouths. The scene cuts to a close-up of the student's eyes, which are wide and dark, before returning to the adults, who now have blood on their mouths and are slumped over the desk, while the student remains motionless. The setting is a classroom or study area with a simple table, chairs, and a potted plant in the background.
