[Reducing Mosaic]MRSS-093 "Let's go on a picnic together again next year..." To earn money for her son's surgery, his beloved wife signed a one-year contract to be a rich man's sex toy. Haruna Yonekura.

Susumu and Yuino's only son, Katsuhiko, required a massive amount of money for his surgery. A wealthy man named Sonoda offered to cover all of Katsuhiko's surgical costs if certain conditions were met. Thus, Susumu and Yuino went to see Sonoda with desperation in their hearts. Sonoda presented the two with an outrageous condition: "I want to hire Yuino as a meat toilet for one year." Susumu strongly opposed it, but yielded to Yuino's resolute desire to save Katsuhiko, ultimately signing the slave● contract.
