I thought the plot for this drama was great. I loved Ji Chang Wook and Song Yoon Ah's acting and characters, they were superb. The thing that ruined this drama for me was Im Yoon Ah's acting and character. Her character was bland, I didn't care for her, and Yoon Ah's acting was boring (and bad...). The romance between Kim Je Ha (Ji Chang Wook) and Ko An Na (Im Yoon Ah) was a let down. If anything, I wish the show had romance between Kim Je Ha (Ji Chang Wook) and Choi Yoo Jin (Song Yoon Ah) instead. Now /that/ would have been interesting... And if not that, then no romance at all...
