Endo plays the role of Daidoji Tamotsu, a 51-year-old department manager in a mid-size trading company who is so immersed in work that he had no chance of getting married in the past. One day, he meets a 28-year-old woman and is so smitten by her that he finally makes up his mind to spend the rest of his life with her. On the other hand, Watabe plays Hanazawa Kiichiro, the 51-year-old father of Daidoji's girlfriend who works in a top-class trading company as the youngest director to date. He leads a happy life with his wife and 3 children and believes that he has the ideal family. Tamotsu aspires to form a happy family with his girlfriend especially after witnessing how the Hanazawa family gets along well with one another but faces strong opposition from Kiichiro who cannot tolerate the notion of his son-in-law being the same age as him and bans Tamotsu from calling him "Otousan".
Endo commented that at his age, it is more likely that he would play a father role but he is very happy to be able to land this character who looks scary on the surface but is actually a kind and honest boyfriend. As the story's premise is very interesting, he is looking forward to playing Tamotsu in his first primetime drama as the lead. In addition, as he has worked with Watabe many times in the past, he is confident that they will be able to produce an entertaining comedy together with their co-stars and staff. On the other hand, Watabe commented that in this age where a lot of the dramas tend to be adaptations, he is happy to see an original story this time and hopes to make a good drama for viewers to enjoy.
