This drama was cute, but having watched the movie first, I've got to say that I kind of expected more on the main story at least. The main difference with the movie, that was a plus for this one and a minus for the movie, was that there were several interesting cases that the agency had to take upon, and most of the drama centred around that. In addition, the main protagonist was cute and bubbly, unlike the movie's who was more of the smart and dynamic. The girl was actually lovable and the love triangle was okay, though the main couple's chemistry was bleak and I would rather had her with the second lead. Also, the drama of the love story was kind of cliché. But, it was a cute drama and it was an easy watch. So, 4 out of 10.
