In episode 18, Junghwan (Ryu Jun Yeol) finally confesses his feelings to Duksun (Hyeri) at the end of the episode.
Ryu Jun Yeol commented on the filming, saying that, “When we filmed [the confession] scene Hyeri cried so much. While she was preparing to act as Duksun, she also personally felt like she was saying goodbye to Junghwan. She probably felt like she wouldn’t be able to interact with Junghwan in the future, and she cried a lot because of it. She cried to the point where we weren’t able to continue filming.”
