Mikuri Moriyama (Yui Aragaki) is a 25-year-old woman whose fledgling career has hit a dead end. She has a degree in psychology and even has a talent for analysing people, but she’s also just been sacked. With no boyfriend and no job, her situation isn’t looking good, especially as her parents are planning to move to the countryside. In a fit of desperation, her father decides to step in… and finds her an unusual job! The job involves working as a live-in maid for a hard-working workaholic (aged 36) named Hiramasa Tsuzaki (Hoshino Gen). He has never had a girlfriend and has no one to look after him. The two decide to live together, but are then forced to get married in order to keep this arrangement going.
