I LOVE this drama. At first, the main girl's "cheerful" attitude was a bit annoying, but I grew to love her. Of course, Song Joongki is wonderful.
I really like the storyline and how they are not mixing in a love line with the already many stories to keep up. If you are looking for a love story, this is not your drama. But if you want suspense and action, yes. The twists and turns this is it for you.
I'm sure the leads will fall in love at the end, but for now, it's more about the cases they are fighting.
