This drama deserve 0.5 higher than 8 and 0.5 lesser than 9. I'll tell you why. The first 3 episodes bored me a bit and then I realized every chapter has a different story so it got my interest. The last 3 eps, surprisingly, were not my fave part. Its dragging and I thought the writer couldn't think of any other reason to keep the story going up to Ep.17. If it ended on 15 or 16 episode, my score would have been a 9. I like the music but it got a bit off in some part. I didn't like the acting of the "Han Na" (not the ghost) but other than that, I don't have issues with the main characters. They portrayed each of their characters well. But, I liked the chemistry of Cha Seung Won & Gong Hyo Jin better in "The Greatest Love" than So Ji Sub. Still, its a different drama. It brings a different joy and excitement to the viewers.
