The Sayuri couple got married on impulse. They live in Tokyo and didn't have a wedding ceremony. Various things weren't settled yet and they hadn't properly greeted the family... so they decided to stay at the husband's rural hometown for a visit.

However, the brother-in-law who appeared was quite a dangerous guy. Every day, he violates Sayuri with his gaze.

She is visually raped, and eventually actually raped — but this turned out to be exactly Sayuri's sexual fetish.
