Lee Joon Gi agreed and said that the director has been behind the details of the scene that though it did not feel much on the set, he managed to make it looked passionate.

Furthermore, Seo Hyun Woo described Lee Joon Gi as an energy booster and didn't get tired quickly. Jang Hee Jin added that they become worried that he'll get tired out. She thinks that he has an unbelievable amount of energy.

Lee Joon Gi noted, "Honestly, I like attention. If I am making fun and run around, then they will turn their eyes on me."
