The story of this was originally what pulled me in, it was creative and something entirely new being introduced to the k-drama land. During the first few episodes, the plot was executed quite well - it was something that hooked viewers and kept them on edge. An hour was extremely short, it almost felt as if each episode was 20 minutes and each episode had a cliffhanger. They left you wanting more. However, as the romance became a main storyline everything started to become messy. Too many plots and conflicts were introduced and it was almost confusing. It felt like the writer rushed to get a ton of ideas in with only 16 episodes. Hence the rating of 8.5. As being an avid fan of Lee Jong Suk's acting and a sucker for character development, I was extremely excited to see how the characterization would pan out. Needless to say, I was both disappointed and immensely satisfied by the end of the drama. All in all, Han Hyo Joo's character and acting turned out to be the biggest let down. I went in expecting a strong and independent female lead with so much potential, as she was in the beginning. However, as it dragged on more and more the only characterization I got from her was Kang Chul's girl. Also, her acting was almost always over exaggerated or awkward. Kang Chul's character pretty much had little development, although having much potential for so much more. Which also limited Jong Suk's acting to that. It was a pity and disappointing with the way the writer went about those two. Surprisingly though, the character that managed to be the dark horse was Kim Eui Sung who played Oh Seong Mo. It was absolutely phenomenal, I found myself pitying him one moment to hating him. Whenever he was on the screen I was completely at the edge of my seat. This particular role gives the drama catharsis and does it extremely well. Besides a couple other characters with the means of comic relief, the rest do not really strike as memorable nor interesting. There wasn't many OSTs, as just a couple were used -- not one of these songs left an impact or were noteworthy. However, the music used did play an extremely good role in setting the mood. Overall, this k-drama was extremely entertaining and a good run. Would recommend it, especially if you need a time filler!
