Yokoyama said that she was shocked and happy about being offered her first leading role but she wondered if she was good enough to take this on. With regard to her character, Yokoyama revealed that she can identify with how Yoriko is misunderstood because of her fierce expression because she herself is always viewed negatively in the same way. As Yokoyama also finds it difficult to convey her thoughts, she felt that the two of them are alike in many ways.
As for the romance storyline with Nakao, Yokoyama praised her co-star for being frank and cute. There was a scene at the coin laundry which was especially memorable to her because it was very sad. Yokoyama also related that Nakao was the one who took the lead during the enjoyable filming process. On the other hand, Nakao commented that Yokoyama was very well-loved by everyone on the set and that she was similar to Yoriko in many ways.
