Amamiya Kuniyuki is the unemployed son of a tonkatsu restaurant owner. He finds a job that requires a married person, so he lies by saying that he has plans to marry, and he is forced to keep up the charade using Tobita Haruno, a part-time worker from the restaurant. The relationship between the two is the key of this romantic comedy, though the series also focuses on family and friendship through Nakai's interactions with the other characters.
