Nakayama commented that as this is the first time that she is acting in such a love-and-hatred drama, she was very eager to give it a shot. When asked about her character Mayuko's tenacity, she commented that although it was frightening, it was also interesting at the same time because her revenge which would turn into pure love at the end is going to be a sad tale. She also said that she can't keep on thinking of revenge all the time and would not recommend anyone to continue bearing a grudge like how Mayuko does. On the other hand, Takaoka explained that her character Yuri admired her buddy so much that she wanted to become her by snatching away what the latter treasured. Perhaps she did not mean any malice at first but her actions had messed up their lives in the end. To show how Yuri would pester Mayuko to give away the things she likes, Takaoka jokingly asked Nakayama to give her the earrings she was wearing but Nakayama retorted straight away that she wouldn't do that which was in contrast to how their relationship was in the drama. Nakayama also chipped in by saying that Mayuko must have hated Yuri for making all these demands but continued to be her friend because she couldn't bear to leave Yuri alone.
As for Ryusei, he was quite pressured to be filming a kiss scene with Nakayama and seeing her bare back and buttocks on the first day of the shooting. However, things got better later and he grew to enjoy the filming even though they had to act in more intimate scenes as the story progressed.
