MRSS-151 Next year, let's go on another trip together... In order to earn money for my son's surgery, my beloved wife signed a contract to become a wealthy man's meat urinal for one year. Kana Morisawa

In order to save the life of her son, who has an incurable disease, Akio's wife, Kana, signs a contract to become a wealthy man named Natsukawa's meat urinal for one year. Akio laments his helplessness in selling his beloved wife, even though it was for his son. The videos sent by Natsukawa every week record the entire process of Kana being trained, and although Kana seemed to have a strong attitude at first, her heart gradually became Natsukawa's.
