This show had all the makings of a great drama, which I would have easily scored 10. It had a fresh story with interesting situations, which certainly made it different from other Korean dramas I've watched and that made it very appealing for me. But as good as the story was, there was one thing which bothered me too much to be overlooked: the main character, Na Mi Roo. This woman was not what I imagined for the main lead of this drama. For me, she didn't fit the concept of it at all. She was annoying beyond belief and a few times I wanted to physically hurt her. At times, it also felt like the character wasn't well written. I didn't feel she had much character growth, if any at all. It was like she was meant to be an ordinary and forgettable supporting character and they decided to make her the main one at the very last minute. So, in one hand we have "loser Mi Roo" and on the other we have Tanya. Now this character was awesome. She was interesting, mysterious, had depth, was funny... In other words, she was everything I had hoped the main character of this drama would be. I also felt she had much more character growth, and was better written, than Mi Roo. Besides Tanya, all the other characters were also interesting and I actually wanted to know more about them and the reasons behind their actions. The wonderful portrayal of those characters was what kept me watching this drama. The OST of the drama was good. I already knew some of the songs because they were in English and the opening credits track was very catchy. And the ending was not common, but not unpredictable since I had a feeling it would end like that. As much as I loved some of the characters (like 4-D writer Lee, awesome Tanya and cute Kwang Woo) and thought the story was very good, I cannot subject myself to watching Mi Roo for 16 episodes again, so I do not ever plan on re-watching this drama again.
