The writing was terrible as if the whole drama had been written by some kid who knows nothing about reality. Usually I don't really mind if the show is realistic or not but I hate it whe the writer uses "the easy way out" and uses some unrealistic even stupid ways to develop the plot. There were a few big twists, but overall the plot was overstretched to the point I wondered if it could be stretched any more. Most of the funny scenes were not funny at all. There was a lot of romance but, in my opinion, the main couple lacked chemistry. They were cute together but didn't have the spark and felt more like friends. On the positive note, the acting was good. Yoochun fit his role perfectly and Shin Se Kyung did great job, I feel like she has develped a lot in acting (she has been on my hate list forever but now I might reconsider). Nam Goong Min was god but I already knew that he is a great actor and didnt expect any less from him! Yoon Ji Seo again disappointed me. She mostly had the same dull face throughout the drama and felt more like a robot than a human being. After a few first episodes the drama gets entertaining for a while but soon slides into the boredom. The police force is downright stupid, I have never seen as stupid cops as in this drama. Well, at least I liked it how the "seeing scents" was implemented, it was very cute. I didn't really expect anything from this show so I can't say I am disappointed. From the beginning, I was going to skip watching it but watched anyway. But I really don't recommend this drama to anyone. It's boring.
