When Kubota got the offer, he was very excited about meeting the staff who also worked on "N no tame ni" with him. However, when he started acting, he got really nervous especially when it came to speaking in the Sanuki dialect. As for Sugisaki who played a teenager suffering from a huge change in temperament due to bullying at school in "Yakou Kanransha", she was eager to see how her role Ayaka would become now that she is an adult but she wasn't sure how she should act. When she started filming, the feeling came back naturally to her and she enjoyed the experience very much.
