This drama contains all level of emotions, from anger to enjoyment, and the cast never failed to express those.
I especially like the fact that there are a lot of plot twists and that these were quite followable.

So in conclusion, this drama is highly recommended if you like a drama that is not too predictable and not so lovey-dovey.

Kudos to the whole cast who convoyed all the emotions very well and especially Lee Seung-gi and Kwon Hwa-woon who had to act as if they were two different persons.
