Miku Hasegawa, a married female teacher working at an all-boys school, is suddenly molested while riding the bus to work one day. With students on board, she fears causing a scene and desperately endures the assault. That evening, as she returns home by bus, her students surround her once again, boldly groping and toying with her body. Mocking her position as their teacher, they whisper, "It'd be bad if students caused trouble, right?" before dragging her from the bus to the classroom, escalating their assault. This series of events plunges Miku into profound humiliation.
