Kamiki commented that the most important part of his character was not about his changes but the fact that Junichi had no intention of changing and yet he couldn't control himself. As such, he had to keep this in mind while acting in this drama. On the other hand, Nikaido revealed that she had no idea why Megumi was so besotted with Junichi after he had changed drastically even after reading the original novel. However, when she started acting in this drama, she began to understand Megumi's mentality. Although this is the first time Kamiki and Nikaido have worked together, Kamiki said that Nikaido is just one year younger than her but she sometimes feels more like an adult with her maturity. Nikaido also complimented Kamiki for helping her as her senior and felt that the trust they had in each other helped them to work well this time.
