Taecyeon detailed his actions scenes with Kim So Hyun in the drama, saying, "Kim So Hyun had prepared many things [for the actions scenes] and she got the hang of them really well so it's a piece of cake for me. If there is one thing that I'm afraid of, it's that I might gain antis because of the footage that shows me hitting [Kim So Hyun] by accident."

Kim So Hyun added, "It's the first time I've really tried action so I practiced really diligently. So the actions scenes went really well and our chemistry was good, too. The scenes show us fighting for real. Because [Taecyeon] would hesitate to hit me, he ended up getting beat up more. It was tough going all out [with the actions scenes] at once."
