This is a show I've wanted to watch for a while but not necessary because it is such a popular one. The fantasy genre is one I really enjoy so I had to give it a chance.

I really liked the idea of parallel worlds; I thought it was a bit tiring in the beginning since they were showing scenes from the past back and forth and you were forgetting what was actually happening in the present but it made so much sense later! I'm one of those who think the drama could have had 16 episodes, there were so many scenes who could've been shortened. There was a certain warmth in some scenes that made me forget about some imperfections. The last 5-6 episodes were so good, a lot of suspense but the last episode seemed a bit rushed. One of the best parts was Nam Doo's storyline from the last part of the drama.

The acting was very good: as always Jun Ji Hyun is great in comedies! She had great chemistry with Lee Min Ho, he did a really good job too. Liked a lot the supporting characters (Joon Jae's friends mostly).

The OST was quite generic.

To be quite honest, I wouldn't rewatch it that much; it started a bit slow but then it really caught up! There were a lot of funny moments though; those need rewatching!
