Tsuchiya commented that it had been a very memorable summer filming this movie last year where she got to try various things and be freed of restrictions. With regard to this, the director said that he didn't give a lot of instructions to the cast and left it to them to do what they deemed best. Takasugi then chipped in to say that this allowed them to enrich their characters as the filming went on. As for being able to do a lot of ad-libs, Mamiya said that it was fun to be allowed to do so and see how Tsuchiya reacted accordingly. As such, Tsuchiya said that this required a lot of fine timing so that they could keep the interaction going and in that sense, it was like a battle of wits between her and Mamiya in the movie.
