The couple Ken and Hitomi were enjoying a happy life. One day, while having a meal at a restaurant, they were approached by two men who used to be their colleagues. The men said they had quit the company and started doing house cleaning, so Ken and Hitomi hired them for the job. Upon visiting their home, the two men suddenly attacked Hitomi… Hitomi was assaulted in a confined space. This was all due to deep resentment towards Ken.
