Kurashina plays the role of Ikeuchi Hikari who works at a design company. Although she was not raised in a rich family, she is a gusty and clever woman who is engaged to a rich guy and her junior at the same company Okugawa Kouta (Miura Shohei). Kouta quit his previous job when he found out that he got it through his family's connections and went to work at Hikari's company. Just when things seem to be going well for Hikari, she reunites with her former boyfriend who she used to love a lot and begins an intense affair with him even though he is married and she is engaged. As a result of this, Kouta becomes very jealous and becomes a different person when he realises that Hikari is drifting away from him.
Otani remarked that he is currently acting in a light-hearted drama "Nigeru wa haji daga yaku ni tatsu" so he is looking forward to switch from that to an emotionally-heavy drama like this and will do his best to show the happy and painful sides of Shin. As this is the first time that he is playing a man who is so dependent and reliant on the women around him, he hopes to be able to show the sexy and dark sides of Shin as well. As for Mizuno, this is the first time that she is playing a baddie role like this who is so obsessed with the man she loves so the viewers will probably imagine her to be the one who will lead every character in the drama to a bad ending thus she hopes to be able to match that kind of expectation.
Other co-stars in this drama include Sakakibara Ikue who plays Misa i.e. Kouta's mother and loves her son so much that she keeps making trouble for Hikari, Kimura Midoriko who plays Maki i.e. Hikari's mother who wishes for her happiness, Miyake Hiroki who plays Takeda Gen, Hikari's superior and used to like her, Akimoto Sayaka who plays Toyono Hideko and pretends to be a good friend of Hikari while trying to snatch Kouta away and Darenogare Akemi who plays Onoue Reika, the childhood friend of Kouta and used to date him during their university days. Nishime Shun will play Shin's junior at work Kato Kiyoshi.
