Secret Garden's�Lee Jong Suk, who played Sun on the show, came on "Strong Heart" and joked around a little bit about his small role in the hit drama. He said, "In the 20 episodes I appeared on the drama, my footage would only total about 30 minutes. All my lines were like 'Go away,' 'Move out of my way,' and 'I'm busy.'" He added, "I had a lot of scenes with Yoon Sang Hyun, and because I was getting a lot of lines in a short time than him, he would yell at me, asking me to talk more." Kang Ho Dong asked him whether or not he feels his popularity. He answered, "I've been feeling it a little. People are recognizing me even though my role was small." Source: My Daily via Nate
