Story:
What made me love this series much was the story. I am a fan of this kind of series. Total respect to the writer. The story was wonderfully knitted as well as the twist. Seems like every scene was a climax. The idea of showing two different time in one episode made me excited with the next episode.

Acting/Cast:
Yeo Jin Goo impressed me one more time. Honestly I'm a fan since. The actors and actresses mad a lasting impression to me. They gave justice to the story as well as to their respective roles. I like the guy ho played as the elder brother in both time. Totally amazing.

Music:
The music made the movie more wonderful to the eyes and pleasing to the ears.

Rewatch Value:
This was a highly recommended movie.

Overall:
I don't like narrating what happened to the movie , my role is to give a review and not to give another synopsis to the movie. So what I have written in this review where mainly base on my personal opinion. Honest;y this movie was really wonderful. It was worth watching for.
