I kept putting off this series because I thought it was something I won’t like , but because I like actor Park Hae Jin in Other Of his series, I finally saw this one. This drama was enjoyable and and the cas was great. The story was well written with some funny parts . I figured out after a few episodes who could be ghost agents. Over all Park acting and action with his many facial reactions added some humors to the story. However the romance between K and Cha was a bit to swallow, Personally she didn’t fit K at all and was bad match , but it’s what they picked, as the leading actress , just like the series, You Who Came From The Stars, the leading lady was to not a good match either. But overall, this series was good.
