All i have to say is that this is now my favorite kdrama. I can't recommend it enough.

You'll have characters that you'll love from the beginning, some that you'll hate and some that you'll have a love-hate relationship with.
I love how the characters develop through the entire drama. I have to admit i hated the female lead a little at the beginning, but the way she changed till the last episode fascinated me. I also love the relationship that bloomed between some characters and it is honestly better than any romantic relationship.

About the end, some characters had a happy end, some not so much. But i couldn't be happier with the ending that they gave us. I think everyone got the ending that they deserved. Of course there are some characters that deserved a little better but it was to be expected and given the circumstances, they couldn't get a better ending.

It's a great drama that will make you go through a lot of emotions in the shortest time possible. It's mysterious and captivating and i promise you, you won't regret watching it.
