This entire Korean Drama is being Pre-Produced...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. This is why it is now expected to air in September 2019.
Interesting fact about Ferny and Tor. At the beginning of May 2019, there was an article about an interview with Ferny. I read it and learned some interesting information about the actress. According to the article, Ferny once met Tor Thanapob in a cafe. This encounter was also the first time she met the actor. Ferny stated that Tor is really like her idol and she is like every other female fan running and asking for autographs and taking pictures with him. Ferny said she never expected to be paired with her idol. She stated it would make other female fans of Tor Thanapob jealous. In spite of everything, Ferny seemed thrilled to have the opportunity to act with him. What a small world!
