I was surprised by how much I enjoyed this. Honestly, after reading the premise, I thought it would be terrible, But Namgoong Min. So, I had to watch it. It was cute. It was quirky. It was clean. The main leads worked well together. Namgoong Min's character...I don't even know what to say. If you are a fan of his, you will NOT be disappointed. At all. There wasn't a triangle, which I liked. The female characters didn't change much, but the changes in the male characters were pretty...stunning. I'd watch it again. Maybe even a few times. PS. As a procedural, it's no good. the Police here DO NOT know WTF they are doing.
