Funny and suspenseful drama! The story itself is good and solid, with overall good characters and great acting, it is very enjoyable to watch. There's not much to say about the story, and I can't say much without giving main plot point away, but it's pretty evident, fight each other -> team up to fight ghosts -> fall in love. It's well played and the show goes from cute/fluffy moment to suspense to plain comedy to slight horror very well and naturally. The ending was quite predictable but good anyway. The ghost stories are quite good and I love the way ghosts are shown in the drama, it's just a bit scary and works very well. Lee David and Kang Ki Young are amazingly funny, make up for one of the best bromance ever and often steal the show. It's worth watching just for them. Lee Do Yeon and Kim Sang Ho are also amazing comic relieves.
