I'm really looking forward to watch this drama even before it airs because the casts are superb! And, to be honest, this kdrama hasn't disappointed me at all. It's like a mind game, and I want to see more! Besides, I like this kind of genre.

The plot, the characters, everything is perfect, and I don't feel like any of the plot is rushed. This kdrama successfully keeps my attention glued to the screen.

This is the best ongoing kdrama I've seen so far, and I'm hoping that it will be successful and that the plot will not be messed up until the end of episode 16. I will update this review once this drama has finished airing to see if it deserves a 10 or if it should stay at 9.5 or lower.

Update: I just finished watching it. A well-paced drama, I think the script for this drama is great; kudos to the writer and director for not wasting valuable talents. Because you know, some dramas have really great actors, but because of the poor script, everything feels wasted. I agree with people who say that the ending feels a bit rushed, but overall, it's still ok.
