I loved this drama so much. I was reluctant to watch it in the beginning because it is not the usual type of drama that I watch. I am so glad I did. The acting was great. The female detective lead was annoying at first when she cried for everything but eventually they improved her character. That is the great thing about this drama they have excellent character development. The story moved along in a fantastic drama way but also in a realistic way. It wasn't just zero to ten, I got to see the reasons the characters changed. I took off. 5 because the ending ruined it for me. It wasn't a bad ending just different than what I imagined.... Overall it was wonderful and I would recommend it to everyone!
