Lee Seung Joon said, "At first, I was very nervous about working with her. I was going to work with not anyone else but with the beautiful actress Song Hye Kyo. But after several gatherings before the shoot I became more comfortable, and that also led to good results in acting."

He then complimented the actress as he added, "She is very easygoing and cool. Song Hye Kyo was also first to recommend staff gatherings to have drinks, and when we did she was outgoing and fun. Sometimes she even paid for everything." 

Sounds like their strong team bond is the secret to their great performance in the trending drama!
