The story and acting were terrific. It keeps you on your toes from the start till the end of each episode. However, there were many times I felt so frustrated that I wished to drop it. I lost count of how many times they lost K. But then again, wanting to see how the story would unfold kept me going. However, it's disappointing that they didn't show in detail Inspector Koo's husband's story. Even Santa-ssi background seemed rushed. Some parts were unrealistic, which I didn't expect from this drama. The Dark Comedy was another highlight of it.

Both Lee Young Ae and Kim Hye Joon did an outstanding job. It was my first time watching Lee Young Ae's drama. And there is no doubt that she is an exceptional actress. I would love to see her more in the future.

I think the drama could have been better. The story seemed to be all over the place, but at the same time, all the puzzle pieces matched perfectly. Many may relate to K. However, if you think from another perspective, you would question, 'Does all evils deserve to die? Do they?'

I wish there was another season with a deeper and darker story. But a wish is a wish. I don't think we are gonna get another one. In short, anyone who enjoys investigation, dark comedy, and psychology must watch it.
