Twenty-eight-year-old Mei Aihara is a single working woman with no time or talent for housework and romance. But when she is forced by her sister to hire Nagisa Shigino, a middle-aged male housekeeper, hilarity ensues.

To her surprise, Mei discovers that her next-door neighbor Yuta works for a rival pharmaceutical company. To make matters worse, her colleague Kaoru arranges for Mei and Yuta to attend a matchmaking dinner together. On top of that, Mei's mother suddenly drops by to visit and Mei has to scurry to hide the fact that she has a male housekeeper!

Mei's mother returns home early to discover Mei and her housekeeper, Nagisa-san, together. Mei confesses that she takes after her mother in being terrible at housework. To Mei's surprise, her mother tells her that she is confident Mei can do anything if she puts her mind to it, and Mei becomes determined to prove her mother right.
