I was aiming for a world championship in swimming, but I was fired when I received a sudden dismissal notice from my company... The reason for his dismissal must be that he witnessed the swimming club coach (Matsumoto) and my ex-boyfriend from college (Otoru) committing adultery in the clubroom... My coach, who has a wife and children, fired me because he was afraid that his physical relationship with Otoru would come to light. Losing my purpose in life and falling to the bottom of her life, I investigated her lifestyle and broke into her company housing with her bad friend. In order to take revenge thoroughly by throwing away the resentment that has accumulated in the pool!
