This one is a rough one. I was considering dropping it after the first few episodes because of our leads. This is no fault to the actors themselves but the male lead just didn't quite fit the role he played though it's still passable. The female lead's role was (yet again) written as a cutesy character who's obsessed with the "cold bad boy" but is just incompetent and unprofessional if you pay attention to what value she brings supposedly as a cop of a special team. Sigh to the Asian draw towards having to incorporate the "cute" even when it doesn't work for the genre, but at least she doesn't wear high heels on the job.

The blend of the crime and romance aspects of the series feels forced/confused as if they didn't know which one to focus on. Then the humor and lightheartedness that was sprinkled on would have worked if it wasn't sometimes done with bad timing. There also wasn't too much chemistry between the two leads and the number of times they made him lean flirtatiously into her face to apparently make her feel uncomfortable (try counting the times) just became an irritating thing to watch. What is also up with the male lead and his alternating of two hairstyles? At first I thought they were attempting to use it to differentiate between the past and the current, but no. Choosing just one or the other would have worked a lot better for the purpose of the character.

Despite all the above however and while the crime aspect wasn't amazing, there is an interesting overall mystery with the male lead's backstory and where it leads. The rest of the supporting cast did a really good job to keep me focused so I quite enjoyed it while skipping the majority of screen time of the female lead.

The concept of society blaming and looking down on (in hypocrisy) the "monsters" they've created themselves is quite evident here which I love. Nothing to do with the actual plot. but let's say a group of children were raised in an environment where murder was as normal and natural as eating a meal, would it be moral to blame the children for living in the same fashion? Then let's say, a few of those children were fortunate enough to later be placed into a gentler and warmer environment, and learned they can feel and live a different way. Would it be moral to punish them for their past deeds from their prior environment? And then to add to the complexity, what if some of those children were just born and wired a certain way?

The strange empathy you may feel for what should be the "monsters" in this is what hits the spot. Who's the one who's really ignorant? Who's moral and who's self-justifying on their own learned morals?

It is definitely very unfortunate that outside of a great underlying plot, the series couldn't pull it off better.
