Only God knows how I wanted to like this drama. I even gave it a second chance after putting it on-hold for almost two years, but unfortunately it fell flat to me.

Since this drama was focused more on the plot and the thriller instead of romance, I'll be more strict judging the story than I usually am cause I had very high expectations for this.

This is not the type of show that'll keep you at the edge of your seat, as it's slow paced and the story takes its time to develop. The first two or three episodes are amazing, all very engaging and efficient at establishing the mystery and the main characters personalities and connections without giving too much away. But after that the drama shifts its focus from the murder mystery and the story looses traction really fast. There were also some dumb plotholes here and there. Jin Gook is constantly withholding important information from his sister just for the sake of creating misunderstanding and keeping the plot going. He also does some poor detective job sometimes, like why would you just leave an important clue you found behind when it's highly likely the suspect will have easy access to it and obviously try to get rid of it? Or how people see someone who clearly attempted suicide and do nothing about it. Also the fact that Jin Kang and Cho Rong dated is completely irrelevant, they don't even act like a couple afterwards (at least not until the point I watched) so why even bother with it?

What bothered me the most, though, was the romance between Jin Kang and Moo Young. I wasn't aware there would be romance in this drama when I first started it and honestly I hated every second of it. I'm sorry but they don't share anything in commom besides their tragic past, every time they meet they fight so how am I supposed to believe they could actually fall for each other? I just wanted the plot to reverse back to the murder mystery and stay away from that relationship cause it was, at least to me, extremely uninteresting to see. I love Moo Young, he's a very unique male lead, cunning, stoic and whose motivations are hard to grasp at first which makes him very engaging to watch, but he is not good as a love interest. Realistically nobody would want to be in a relationship with someone so annoying and hard to figure out with that devil-may-care attitude of his, specially not someone who's initially so level-headed and mature like Jin Kang so that's why I couldn't immerse myself in the story anymore.

The acting is top-notch, though. After seeing So In Guk in Shopping King Louis I was extremely surprised by his portrayal of a polar opposite character here, it was astounding. Jung So Min does a very good job as well and I think all the cast is pretty good with their acting. The soundtrack is also great, it helps to create a very eerie and enigmatic atmosphere throughout the narrative.

All in all it's definitely not terrible, but it was a great disappointment to me. I unfortunately read a spoiler about the Japanese drama and I thought it was a really unexpected revelation, which would've potentially made this drama worth watching, but I just couldn't keep myself interested enough to get to the end. Even so, I'd still recommend it for people who wish to see some drama with a different atmosphere from your typical Korean romance.
