Let me start with I loved Park Bo Young in this series. She was wonderful playing two roles so differently. She was the best part of the whole series. I did not like the forced love triangle. The ghost was interesting and best when she was investigating her death not when she was trying to seduce the male lead. I was more invested in her discovery than anything. It was not terrible but I do not see myself re-watching the whole series, just the last three episodes. The music was fine but nothing that stood out to me.
