Yoon Gyoon Sang played Lee Jong Suk's revenge-driven brother Ki Jae Myeong in "Pinocchio." Jae Myeong was a complicated character, having no compunction about cold-bloodedly killing those responsible for his father's disgrace and at the same time, risking his life to save a stranger from being run over.

It was a complicated role to play, said Yoon in an interview with the Korean media outlet Sports Hankook.

"I went through a lot of mental stress," said Yoon. "It was an emotionally consuming role to play. I think it would've been better if my character were a psychopath. However, Jae Myeong is a good kid. He had a lot of anger bottled up inside him. He was a miserable one."
