Production

On February 16, 2017, the series was renewed for a second season.^[6][7] 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.^[19]

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 due to an bullying incident regarding her group, T-ara.^[20] 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.^{[21][unreliable source?]}

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.^[22]
