I started watching this show after watching 'Oh My Venus' because I just LOVE the main actor and wanted to see more of his work. He is still absolutely lovable and funny in this one even though He started out cold he was able to do it without being a typical jerk and it was always hilarious how money driven he was. The main actress...I did like her but she had moments when I just was so frustrated with her because she was so thoughtless in getting involved in ghostly situations. She does eventually find a balance in her life and finds confidence which I do love but how she went about finding it was unnecessarily difficult at times. Overall I loved the main couple, I shipped them so hard. Besides Joo Joong-won, my other favorite characters were Secretory Kim and Tae Yi Rung. There are so many loveable secretorys in kdramas but Secretory Kim is one of the best. He is a shipper like the rest of us and is almost more of a fatherly figure than anything else. You can tell just how much the main guy adores him and needs him. I adored Tae Yi Rung...she was the freaking highlight. I thought I was going to hate her since usually the woman who dislikes the main actress tends to be horrible but she was an absolute joy. At times I felt she was much more interesting than Tae Yang. This Drama starts off in the scary side but after a couple of episodes it ceases to be which kind of goes with Tae Yang getting more used to the ghosts. The stories behind the death of some of these ghosts and why they haven't moved on are also a big part of the drama and really is where are all the heart lies. I cried many times. I wish it could be explained why Joo Joong-won was the only one who is able to make ghosts disappear for her but they did explain how she comes to be able to see ghosts. Overall, Great drama! A must watch :)
