Everything is excellent. This is a Korean drama must watch. I could give a rating beyond 10 if willbe given a chance. You will fall in love over and over again plus there are thrills and exciting factor. In addition, the actors and actresses are very good in their acting slespwcially Moon Chae Won. The storyline is quite unpredictable and exciting.it wont affect you emotionally lone, but it will lasts lesson also. I'll definitely watch it again and again. Kudos to all the production team for a superb product!! Keep it up!
