This is Oikawa's first leading role in a drama in 10 years since 2004's TV Asahi drama "Mystery Minzoku Gakusha Yagumo Itsuki". Although he plays good characters most of the time, Oikawa is happy about playing a dark hero this time which is a good form of stress relief. He also praised Kuroki who he is working for the first time, for being a very cheerful person who can switch to becoming a cool beauty quickly which is a trait he deeply admires. As for Kuroki, she commented that her character this time will be a tough one to play so she has to work extra hard on portraying the character.
