A dark network lurking within a prestigious tutoring academy forces high-achieving girls into prostitution. Unaware that their acts are being recorded and released as adult videos, these girls comply out of fear of being bullied. Among them is a bespectacled girl whose intelligence is evident in her demeanor and speech, calmly submitting to the man. However, unsatisfied after a single encounter, the man binds the girls to the SM equipment in the room and torments them with sex toys. Restrained and unable to move, the girls, overwhelmed by these unfamiliar sensations, writhe and thrash wildly. Their agonized ecstasy sends chills down the spine, radiating an eerie, unsettling allure.
