A case of backdoor admissions brokerage took place at a prep school. Yukino, a lecturer, witnessed the incident by chance. Later, someone made an internal whistleblower report, and those involved in the backdoor admissions were arrested, and the prep school went bankrupt. Yukino made a fresh start at a new job, but on her way home, she was attacked by someone and imprisoned in a dungeon. The wife of the school principal, who was arrested for backdoor admissions, stood before her with an angry look on her face. A humiliating Yukino, and a retaliatory enema party held by a foolish parent and child!
