The show was inspired by The First Years of the Undercover Bimbo (2011), an episode of Naor's Friends (2006). Three of the episode cast play the same characters in this show: Ania Bukstein (Silvy), Shmuel Edelman (Simcha Apple), and Rotem Zissman-Cohen (Ronit). Anat Magen, who played Shontal in the episode, was replaced by Neta Garty in the show.
The original names of Shani, Slavit and Chen are: Shontal Swissa, Silvy Knafo and Cheli Abargil respectively. Ronit is the only of the group who has not changed her name.
