Tsumabuki plays the lead character Sasaki Shinichi who works as a cleaner and believes wholeheartedly in the innocence of a woman on death row despite what the world thinks of her. The woman in question i.e. Tanaka Yukino is a childhood friend of Shinichi and is given the death sentence for setting fire to the apartment of her ex-boyfriend and killing his wife and children in the process. As Shinichi knows Yukino since they were young and has been indebted to her due to some reason, his instinct tells him that she can't be the killer and goes searching for people who feels the same way. However, as he digs deeper into Yukino's past, he finds out a totally unexpected story and truth behind the case.
Takeuchi Yuko will play Yukino in this drama and described the character as someone who has a strong desire to be needed by someone and goes all out to devote herself to whoever needs her. As such, she is seen as an easy woman and childish at times because of her tendency to have a strong attachment to the person she loves. Regardless of how Yukino turns out to be, she is still trusted by Shinichi so Takeuchi said that this was what really left a strong impression on her.
Arai Hirofumi plays Tange Sho, a lawyer and childhood friend of Shinichi and Yukino. He commented that he was honoured to be offered a chance to participate in this drama produced by Tsumabuki and cited their collaboration as the selling point of this drama since he claimed that he has worked with Tsumabuki the most number of times to date.
Yoshine Kyoko will play Sadoyama Hitomi, the prison officer who interacts with Yukino and is torn between her sense of duty and humanity. Yoshine commented that she was coached by a former prison officer in preparation for the filming and that her character's perspective should be closest to that of the viewers as an observer of what's going on.
Other co-stars include Tomosaka Rie, Hasegawa Kyoko, Ikeuchi Hiroyuki, Yamanaka Takashi, Ashina Sei, Satsukawa Aimi, Kiyohara Kaya, Taguchi Hiromasa, Hara Hideko, Ishibashi Renji and Yo Kimiko.
