Nice Guy is my first melodrama and I totally like it!! The show has all ingredients of a typical melodrama but it has that touch of a thriller which makes it all different. The story is about a guy who sets out to take revenge from his girlfriend, who betrayed him.In the process, he uses a cold-hearted girl and falls for her instead.Well the story is nothing new but the treatment is.It is full of twists and turns. Song Joong Ki plays his role perfectly.Moon Chae Won is fantastic and Park Si Yeon has acted really well.All other cast members have also done a great job. The only thing that went for downside for me was that the emotional link with the characters was not that strong. All in all... an interesting drama.
