The filming of the drama took place near Nagoya between September and December last year as it is a NHK Nagoya production. When asked about the filming process, Haru recounted that it was a very intense and painful time because of the story which will keep everyone on tenterhooks. She also commented that thanks to Saito's acting, it has helped to make this a beautiful yet scary drama. Meanwhile, Saito said smilingly that she plays a really frightening mother in the drama and there were many emotional scenes between her and Haru which were quite draining mentally. In addition, she had to spend quite a bit of time at Nagoya and leave her three children at home so that made her feel quite bad at times. Although she cannot identify with her character's ways, Saito had tried her best to play the mother and hopes that everyone will like the drama. As for Yagira, he remarked that this was the first time that he was surrounded by a largely-female cast so he was quite happy during the filming.
