This drama ticked all the boxes: good character dynamics and a plot that tackles some pretty hefty themes without any over-the-top depictions. Act one was especially good at keeping my attention and building the story, and the second act fully developed most of the characters while exploring their motivations. All of this build-up to the reveal of the big bad, and then it goes downhill from there. I feel like the expectations created during two-thirds of the plot are very different from the end result. Instead of a cold and calculated serial killer with strict personal morals, we got an unhinged maniac. What was his deal anyway? He couldn't be with his girlfriend and decided to murder everyone because being sad is bad? The nurse was much better written to be honest and was overshadowed by the idiot in a white suit.

On another note, this drama is the first one where I liked the soundtrack. So I'm saving the ending theme for later.
