Moriyama Shikuri (played by Yui Aragaki) has been in a bad career since graduating from graduate school. Recently, she was fired and was in a state of "unemployed vagrant". Her life was very miserable. Through her father's introduction, Shikuri, who had nowhere to go, came to the home of a single man named Tsuzaki Hiramitsu (played by Gen Hoshino) to do housework for him. In this way, the 25-year-old Shikuri became a housekeeper. Shikuri is kind-hearted and hardworking. Under her arrangement and labor, everything in Hiramitsu's home is well organized. Shikuri therefore gained Hiramitsu's trust, found the focus of life, and cheered up again. However, the good times did not last long. Shikuri's parents decided to move away, which meant that Shikuri had to "resign". Shikuri, who really couldn't accept this, decided to "contract marriage" with Hiramitsu, pretending to be a couple outside, and still being an employer and an employee inside. In this way, this pair of "lonely men and widows" began their cohabitation life.
