Controversy
On January 24, 2018, a photo was shared online saying that lead actress Kim So-hyun was shooting underwater. The photo shows a woman wearing a hanbok in the water on January 21. On that day, the lowest temperature was recorded below -16 C. During the press conference for the premiere of Radio Romance held on January 25, the drama's PD addressed online criticism regarding the outdoor water filming, despite the weather warnings. He issued an apology stating that "Kim So Hyun's outdoor water filming wrapped up on Sunday (Jan 21st). We debated on it a lot, since she would be getting in the water. We ensured safety equipment nearby, as well as a camping car on set, and finished filming in the shortest amount of time possible. Due to time constraints, an action stunt double filmed additional outdoor water scenes yesterday (Jan 24th). It was filmed by an action actor, not Kim So-hyun, wearing a winter suit and shot in a similar situation (Jan 21st). The number of shots was done with one take and protection was taken right away. We apologize for causing concerns with this matter. The filming set is our life. Naturally, safety is important." At the press conference, Kim's hand was seen red.
