Ji Chang Wook said, "First, our chemistry is great. The chemistry is great with Song Yoon Ah and also with Im YoonA, and we talked at great length on set. I think we became close getting to know one another just talking and discussing the drama. YoonA's personality is bright. I think she is an actress who gives laughter to all the staff members on set. After talking to her, I realized that she is someone who is very obsessed with and ambitious about acting and thinks a lot about it. I got the thought that she is an acting partner that I can trust."
