Really Good story but the Cast spoiled it there is no acting in both the main roles .. The girl's acting sucks!! I feel there is no need of the female lead Yoo Kang Mi.. Only the cheif of NPAC Kwon Hyuk Joo does some acting i really like his role.. I dont understand why the male lead only have a grim expression all the time.. though i havent completed the serial yet till 16th episode the story is really very good... There is no feeling of the urge to watch the next episode as it is little dull because there is no comedy inbetween to relax the mood ... Overall a good Detective series Can watch for the story.
