I'm new to Kdramas and this was the first series I watched with LDW in it. I have since come to realize what a great actor he is, because when I watched this the first time I thought this was his real personality. I knew he was acting, but so many actors keep their personalities in projects to such an extent that you can always see the actor behind the character. It was only after I started watching Tale of the 9 Tailed that I realized my mistake. 

Every gesture and expression of his was true to this character in a way that makes him seem like he truly is like the man he portrays. On the one hand I wish more of the world knew of this amazing actor, but on the other hand I'm so grateful Hollywood hasn't gotten it's soul destroying hands on him.
