Suzu, who can't refuse anything asked by others, was living a comfortable life with her husband. However, there was one problem... her brother-in-law Akira, who didn't get along with her husband. Following her mother-in-law's advice, they let the divorced and unemployed Akira live with them. One day, desperate Akira asked to see her naked, and reluctantly, Suzu agreed. But this was just the beginning of Akira's plan to turn his sister-in-law into his girlfriend, and innocent Suzu had no idea.
