Out of all the actors that I have watched, Lee Jong Suk is my favorite. He is such a talented actor that he gives justice to each character that was given to him. So, I decided to watch all of the dramas that he was in and that is the time when I stumbled upon this drama, While You Were Sleeping. This drama has everything that you could ever ask for and it also gives you twists and turns that you would not expect. Everything is intricately connected with one another and that is what I love about the writing of this drama. This drama kept me on the edge of my seat every episode, it kept me intrigued and curious consistently. But among this serious atmosphere that the series offer, there is also a comedic side to balance everything out. It's really the perfect balance between thriller and comedy. The overall plot of the story is easy to follow and I love how the show uses the concept of 'butterfly effect' to deliver its plot. However, I feel like the plot gives the spotlight to the characters of Bae Suzy and Lee Jong Suk too much that they overshadow their co-actor Jung Hae In. Jung Hae In is an incredible actor and he gave justice to his character however the script or the plot did not give him the spotlight that his character deserves. Well, that's just me being nitpicky but all in all the plot is good and well-written.

Each and every actor in this drama really gave justice to their character. I would like to praise Lee Sang Yeob in particular. He really gave the drama the antagonist that it deserves. Normally, we could pinpoint easily who the antagonists and protagonists are but this drama did it a little differently. Yes, you could easily recognize who the 'bad guy' is however have you ever tried to put yourself in your antagonist's shoes? This drama reflects the inner conflict that the antagonist, Lee Yu Beom is facing. You could see that he despises the cruel things he did but he thinks that he does not have the choice. Sadly, the drama did not go entirely on this route, so I think that it was a wasted opportunity. But even though they did not go through that route, they still did a good job with the plot and ending.

The soundtracks are also good especially the timing when it is played. It really helps connect the viewers to the scene. But not all the songs are memorable and I think that is the problem. Don't get me wrong, they are great songs but they are just not that memorable.

So, would I rewatch this? Of course. This is one of the few series that I would like to rewatch if given the chance. I would also recommend this to the people I know. This is such a good k-drama. So, if you ever have hesitations please throw them out. You won't regret watching this.
