Even though the drama was short, I loved every minute of this drama. I was waiting for this before it aired and I was hyped. I am glad that I ended up watching this drama. There were math problems that I have never heard of before & the cases kept you interested. The thing is I love the leads! They so opposite of each other, but they make a great team. I haven't seen the female lead in anything before, but she was great. I think I have seen the male lead before, I don't remember which movie or drama that I have seen him in, but he is a great actor as well. He is also hot. . . I had to say it. . . The only problem with the drama is that we didn't get to learn much of their background at all. They have great chemistry despite the age difference. But don't let that turn you away from watching this drama. The music fitted in the right spots, theme is catchy, but I don't remember much since it was a long time ago when I watched this drama last year(2013). I would re-watch this again when I have time. Overall, I definitely recommend this drama if you like crime genre, math, comedy & cases that keep you guessing, then you will like this one. The only complaint besides the one I mentioned above, is that it should of been longer.
