I really enjoyed this drama. The story is a big unique in terms of the special abilities/conditions. It has enough romance to satisfy romance-addict like myself while also keeping the non-romance crime suspense storyline. The pace was good, not too slow but not rushed either. It also has a couple of great reveal moments.

SPOILER:
My only complaint (and this is totally personally petty me) is that although Namkoong Min did a good job, I don't like seeing him as a bad guy just because I like him and tends to want to root for him.

Oh and this drama has one of the most unique, creative, and sweetest proposal ever.
