The drama features Kurashina as the heroine who has a fiance played by Miura but reunites with her former boyfriend who is already married (Otani) and begins an extramarital affair with him. Mizuno plays the wife of Otani's character who is obsessively in love with him. Kurashima remarked that as the filming progressed, the biggest challenge was how to come to terms with the feelings of her character who had to be prepared to make certain sacrifices if she wanted to do what she wanted even though it might not be the right thing to do. In addition, as the script was full of intense and heartstopping moments, it felt like a very stimulating work to her. Miura echoed her view and said that he was very excited about playing his character who was consumed by jealousy and do very drastic things.
In relation to the story's theme, the cast were asked if there was anything which they felt jealous about recently. Miura cited the example of seeing his fiance (Kurashina) and her ex (Otani) hugging while Mizuno joked that it was when her "husband" was kissing Kurashina.
