The premise was excellent and the first two episodes caught my attention right away. Then came the disappointment... There was really nothing interesting to this story and it turned out dull. It had great potential but the show never went into depth about anything at all so the plot turned out superficial. The side characters didn't really have any backstories and the cast didn't have any sort of unity that would have made them into a group of people fighting for the same goal. Eventually it became really hard to care for anyone in the story. I love these type of corporate plotting dramas but Korean detective dramas are usually very tasteless so I wish there was no police involved her either. When it comes to antiheroes or 'bad guys turn good' - plot lines Korean do really well as long as the story doesn't concentrate too much on the romance. Even though there was a lot of plotting and dirty games going on I felt like most of the drama was about love and the plotting scenes became repetitive. The bad guy was really obvious too... The acting was good, except for Kim so Yeon, her character was really dull. even though she was supposed to be mature she was leaving the company all the time for personal reasons but then stuck around after all... I must say that the best one was Lee Shi Eon, this guy really has talent. His character came to life on the screen. Ahn Suk Hwan never fails as the father figure. Jung Kyung Hoo was good but his character wasn't interesting. In the beginning he caught my attention and his character had the spunk but after the surgery he changed into a mess. I wish the writer had paid more attention to character development.
