Ienai Koto wo Shita no wa Dare?

A school nurse at a junior high school receives an unexpected phone call that initially seems like a prank but soon reveals a deeper significance. At the school, teachers wield considerable authority over students, often intruding on their personal lives without consequence. The students, still young and emotionally vulnerable, become targets for serious misconduct, including sexual harassment and assault. The nurse becomes aware of a past incident at the school and realizes a similar event is occurring again. Her role, the school administration’s resistance to change, and the victims’ reluctance to speak out all hinder her efforts. She faces these challenges alone in her attempt to end the pattern of abuse and help those affected.
