Kyoko (Age 30) was betrayed by the man who promised to marry her, and spends her days in a deep depression. At her friend’s suggestion, she tries out a dating app, where she meets Kadono (Age 28). She falls in love with him and they get married. Kyoko is head over heels for the handsome and kind Kadono, but it doesn’t take long at all for her to start wondering if her husband’s kindness is all a lie, and he’s actually seeing another woman. Kyoko enlists the help of Nomura (Age 43) to investigate him. Nomura tells her that except for spending a lot of time at the condominium where he works, her husband has done nothing suspicious. Still doubtful, Kyoko asks him to investigate further. He reluctantly agrees to plant listening devices in the condominium. Later, he contacts her saying he has an audio file for her to hear. Kyoko doesn’t have the money to pay for the extra investigation, and agrees to Nomura’s demands that she sleeps with him instead. The audio file he gives her shows what appears to be Kadono talking to another woman.
