Yeon Woo Jin went from a mysterious aura in all black, then to a lighter tone dressed in all white. He didn't leave out his boyish charm as he casually wore a plain t-shirt and a pair of ripped up jeans with sneakers.
In order to fully prepare for his role as Lee Yeok, he mentioned, "I studied the Records of the Joseon Dynasty and also worked hard in action sequences."
When asked about his ideal type of woman, Yeon Woo Jin answered, "I would prefer someone who is like a friend. My ideal type has gradually changed as I've gone from project to project."
