Absolutely stunning.. despite some little details I could not bear (no spoiler), I must give this drama a full 10.It worth watching even if you don't agree with the ending.. It worth for the strong adult story, the crime scene, the OST, even the annoying detective..For people that doesn't accept the ending, I mean they deserve this kind of ending, I will not say anything more, but HEY this is NOT a typical korean drama with a nonsense ending ..!! I loved even the ending, It gave me goose bumps..!!!!I loved every single characters of the story and the actors were all amazing..!!! ......this is a MASTERPIECE!!!!!
