At the time of filming, they said, "We don't know the previous story, so we're just acting as it flows, haha."

The production team asked about the future relationship between Wan and Hee-joo or the plot's development. IU replied, "I also saw the script for episode 10 for the first time on the day we were filming this scene," adding, "Even if I wanted to give you a hint, I really don't know. I'm acting without knowing the situation leading up to it myself, so I'm just going to let it flow." I really enjoyed watching it!
