Nakagawa commented that he was surprised to be getting a role for 27 years old even though he is only 18 now. However, he saw this a new challenge for himself and was glad to be given the chance to give it a shot. As for how to show the 10-year age gap, Nakagawa revealed that the staff had helped him to look the part by making adjustments to his appearance. As for Taira, she had to cut her fringe to match the image of her character and has started to develop an interest in cats since Hishiro is a cat lover.
Filming begins in early November.
