But there's a problem… it was Akira, her brother-in-law, who was not compatible with her husband. A day after several days had passed since Akira, who was divorced and unemployed, was allowed to stay at Misuzu's house on the recommendation of her mother-in-law. Misuzu reluctantly accepts Akira's desperate request to see her naked. However, Misuzu, who is innocent, cannot know that this is the beginning of her brother-in-law Akira's plan.
