Filming began in June 2018 and the series is entirely pre-produced. Overseas filming took place in Portugal and Morocco.
This is the second time actors Lee Seung-gi and Bae Suzy have worked together on screen. They previously starred together in 2013 MBC drama series Guga-ui Seo (2013).
Originally scheduled to air in end-2018, the series was pushed back to May 2019, and then again due to filming schedule issues and a pending deal with Netflix. Finally, it aired in September 2019.
