After being married to Sumire for several years, they were living a happy life together. He was doing well at his job and even though he sometimes caused trouble for her, their relationship remained stable... One day, when talking about getting married with his junior co-worker Soseki, he said that marriage wasn't something he was interested in or hoped for. So, to prove how great marriage could be, he decided to have a pretend husband experience with his wife. They spent three hours alone together, just the two of them, and Soseki seemed to understand the joys of marriage by the end of it. A few days later, when Soseki asked if he could come over again today, he thought it would be fun to set up a hidden camera since he had an idea for some playful games.

妻のスミレと結婚して数年。会社でも昇進し仕事で迷惑をかけることもあるが妻とも順調に過ごしていた…。ある日、後輩の左慈と結婚の話になり、興味も希望もないと言うもんだから結婚がいかに良いものか分からせる為に妻と擬似夫婦体験をさせる事にした。それから3時間、2人きりにしただけで左慈も結婚の良さを理解した様だった。そして数日後、今日も家に来たいと言うので弄るネタにしようと隠しカメラを仕掛けたのだが…。
