When asked about his impression of Kita Senju where they did all the filming at, Tsukamoto recounted that the area used to be known for being crowded with gangsters and scary people but it turned out to be a place full of warmth and has its own rules and policies. As for Koike who is working with Tsukamoto for the first time, the two of them had to act in a manzai skit on the first day of the filming but they acted so naturally as if they have been a comedic duo for ages.
Higa whose character in the drama is rather headstrong, was revealed to love her hometown Okinawa so much that she would get worked up if people joked or made fun of it. Tsukamoto said that there was a scene in the drama where Nobara was scolding Keigo for making fun of Okinawa which Koike echoed that Higa behaves the same way in real life. In response, Higa jokingly told them off and wanted them to stop making fun of her hometown.
