Story: (Rant)
I regret complaining about predictable dramas, this was so frustrating when I cared about the outcome but I stopped caring about halfway through and lost all interest, I completed watching it for closure.
Basically imagine being a blind person that follows sounds, and the writer keeps tossing pebbles around you, they toss one, you take one step there, and they toss one on the other direction, and it's not only 2 directions, but like 3 or 4.
Instead of just making it mysterious, they forcefully led you to the wrong direction over and over until the last 2 episodes where the ending is finally starting to clear.
It was so frustrating that some characters KNEW what happened wouldn't just fess-up when they aren't even awfully evil, they just DON'T want to talk, or empathize with the main leads.
The result of all of this is a rushed ending where suddenly all the evidences appear, and witnesses talk, to close the drama.

Cast:
They were okay, like other comments and reviews said, the chemistry and romance between the leads was awkward, also at this point, I think Eun Joo's teeth were glued together, unfortunate since I was looking forward to her performance.

Music: It's alright if you're into classicals, but if you're not I don't think you should watch this drama at all, since this is the best part of it compared to the rest.

Rewatch Value: Honestly, once you know the ending there is really nothing remaining in rewatching it unless you want to laugh at the pebbles the writer kept throwing left and right.
