The story is based on the same-titled novel by Shouji Yukiya where Nakai plays the lead character Kunieda Takahiko who raised his daughter Miki (Haru) singlehandedly after his wife Yoshimi (Okunuki Kaoru) passed away. When Miki tells her father that there is someone she would like him to meet, Takahiko tries to avoid this meeting for some reason. The man who Miki wants to let Takahiko meet is actually her fiance Shin (Mitsushima) who was her childhood friend and is the son of their former neighbours Furuichi Toshiyuki (Mitsuishi Ken) and Keiko (Kimura Midoriko). The issue is, Keiko is a well-known troublemaker in the neighbourhood and seemed to have some disagreement with Yoshimi in the past so Takahiko is troubled over how to tell Miki about it. Just then, Takahiko meets his ex-girlfriend Kataoka Ayano (Harada Mieko) back in university by chance and discovers an unexpected connection with her as he grapples with the reality of his daughter's impending marriage.
