I was aiming for the world championship in swimming, and I got fired after receiving a sudden notice of dismissal from the company. The reason for the dismissal must have been that he witnessed the fornication in the club room of the swimming club coach (Matsumoto) and my ex-girlfriend (Otoru) in college ... A coach with a wife and children fired me for fear of discovering a physical relationship with Otoru. Losing the purpose of living and crashing to the bottom of my life, I investigated Otoru's lifestyle and broke into a company house with a bad friend. In order to get rid of the grudges that have accumulated in the pool and take revenge thoroughly!
