Katori commented that his character is exactly the same as himself and joked that he has many real-life examples near him to help in playing this role i.e. his fellow SMAP members Nakai Masahiro, Kusanagi Tsuyoshi and Inagaki Goro. He said that all of them are men who can't get married but for different reasons so he wants to take elements from each of their situations to integrate into his role. As for his first collaboration with Ueno, he expressed his impression of her as someone who is unpredictable thus he is looking forward to the chemistry between them when they start filming. On the other hand, Ueno expressed her interest in playing someone who is not that keen on marriage and hopes that the interaction between her and Katori as well as the people around them will let the viewers see the importance of family relationships and what it means to get married and form a family.
