Nam Ji Hyun shared, "Ha Neul oppa and I are around five years apart, but the five-year age gap seemed small because [Kang Ha Neul] oppa treated me very well. I was able to enjoy filming thanks to him."

She also chose her favorite scene: "It was my first time bungee jumping. It was something I always wanted to do so through this drama, I was able to go bungee jumping three times in a row. I had a lot of fun, but Ha Neul seemed like he was a bit scared."

The child actress also handled her kiss scene maturely, sharing, "Since it's acting, it wasn't very embarrassing or anything like that. I was a little nervous because it was my first time doing it, but I wasn't very nervous or anything like that... I'm twenty years old, but I have not experienced my first love yet. It's still an unknown world to me."
