Misuzu, who has a personality that cannot refuse someone when they ask for something, has lived a comfortable life with her husband. But there is one problem... it is Akira, her brother-in-law, who does not get along with her husband. One day, a few days after Akira, who is divorced and unemployed, was allowed to stay at Misuzu's house on her mother-in-law's introduction, Misuzu reluctantly accepted 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.
