This K-drama was worth watching. Woo Do-hwan’s character was a lot more lovable than the lead portrayed by Yang Se-jong. He endured more pain, had better discipline and control over his revenge and sacrificed for others without any support from friends, only misunderstandings. Because of this, his mistakes become more forgivable. Alternatively, the main character’s thoughtless outbursts, betrayals and actions looked more self serving and less heroic. I would definitely watch more movies with Woo Do-hwan - great acting in this one!
