The plot is weak. There are few cute/fluffy scenes but not that much. There was some funny scenes, but not that much, and also some mystery but not that much. To summarize, everything was kind of so so.
To be honest, I was able to finish it only due to Lee Jung Suk. He's cute, everybody knows that, he's a very handsome and good actor, that saved this drama. The lead actress wasn't bad, actually she's very good, is just the writing. I feel like I wen't trough the whole 16 episodes for the sake of looking at LJS's cute face and that's it.
I don't get it how this drama was able to score 8.5. Maybe it's the magic of having LJS in the cast.
