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.
