Production
On February 16, 2017, the series was renewed for a second season. It was announced that Ryu Hwa-young would only make a cameo appearance, and that a new actress would be cast as the fifth girl of the Belle Epoque.
Originally, it was expected that all five main roles would be the same from the previous season. However, early on Ryu Hwa-young was removed from the main cast. Instead, a new character, Jo Eun, was created to fill the five-person dynamic of the show. Park Hye-soo was also supposed to be part of the main cast, but due to a scheduling conflict, she stepped down from the role. Unlike Ryu Hwa-young, this happened late into pre-production and it was decided that another actress would play her character Yoo Eun-jae; Ji Woo was cast.
Onew was originally cast in the role of Kwon Ho-chang, but he stepped down in light of controversy surrounding him ten days before the drama's premiere, and was replaced with Lee Yoo-jin.
