Sara, a 21-year-old female college student. She works at a girls' bar at night. Her ex-boyfriend was a very sadistic person. Every time she remembers being awakened to the pleasure of masochism, her loneliness grows, wishing she could return to those days. It was at that time that she discovered the existence of the club. I heard that it fulfills the desires of unfulfilled women. I want to immerse myself in the pleasure of masochism once more.
