Even though Kang Ki Young did not have many scenes with the male lead Lee Jong Suk, he said he could still tell that Lee Jong Suk is full of aegyo. "When I saw him, he would come up to me saying 'Hyung', and even hugged me when I arrived. I tend to be timid so it was hard to get used to at first, but it got comfortable because Lee Jong Suk was nice to me. The director and other staff members also liked [Lee Jong Suk's aegyo]," he said.
Next, he complimented Han Hyo Joo, and said, "The chemistry between me and Oh Yeon Joo was great. It's all because Han Hyo Joo treated me comfortably. To be honest, Han Hyo Joo was a superstar to me at first, but now, we've dropped the honorifics, and sometimes even joke around on SNS. I think that's why our chemistry was able to live better. I was happy to meet with a good actress."
