While discussing his drama in a recent interview, Ji Chang Wook also shared about his chemistry with his co-star Girls' Generation's YoonA, and said, "We talked a lot. The kiss scene that was aired near the end was actually filmed first when we were overseas for filming. We found out that we'd be filming that scene when we arrived at the Barcelona Airport. They told us that we'd be filming a kiss scene in several days. There wasn't a completed script yet. The screenwriter just told us the situation. I was so startled so I told her (YoonA) that we should get to know each other fast. It was really pressuring. We had to get close because of the kiss scene. So we talked a lot about the drama and also shared about each other. We shared our perspectives, how we lived our lives, hobbies, and even nonsensical life philosophies, and we became close real fast."

Ji Chang Wook then explained the kiss scene in detail, and said, "I was so worried after seeing the script. In the script, it was a scene where we have a blanket over us and I hold her like a bodyguard and then kiss. We talked about how to make it fit into the situation in a fun way and a lot of it was done by ad libs. I heard the scene is about 3 minutes, and to be honest, having my arms up for 3 minutes made my arms hurt. It wasn't easy." 

Well, it seems like their hard work paid off! How did you enjoy the "blanket kiss" in 'The K2'?
