Who is this actor ?

He was in episode 16 and 17 I think a reporter something oh but I don't see him on the cast list or dramawiki. But he looks really familiar. I can't find a picture of him he may be just a cameo. I hope someone remembers or know who I am talking about.

Oops romantic doctor and I think I remember could he be same actor that played in tv tunnel series or not?
