I'm ganna start by saying that I really don't understand why people are giving this a low rating. It is an amazing mix between cute romance and interesting criminal plot twists. I think these two were complementary, making the drama so interesting to watch. The romance with all its ups and downs never felt annoying or cliched-there were always good reasons for the relationship alterations to occur. And obviously, Ji wook's character is so appealing and adorable. Also, whenever one thinks the action is over, something even more surprising happens. I garra mention again that it really never got cliched or boring. The plot is very solid. Finally, the OST in this show is of the best, specially the sadder ones. I wonder how this show could hold so much comedy and sadness at the same time. A truly brilliant story.
