The plot is really unique showing a blurry present while slowly revealing the past bit by bit in each episode. Each episode revealing more and more about what truly happened to the main lead. The chemistry of the leads is off the roofs on screen and off screen. The first 12 Episodes were FANTASTIC but the final 4 were slightly confusing. Writer nim definitely had a hiccup towards the end but the suspense and build up of whats going to happen through out the drama will make you stick with it. JUST give it a shot AND YOU WILL LIKE IT.
