Noooooo...
I'm so sad it had to end...
I-I just want a season two even though I know it's pretty impossible. One can dream though.
I was so tempted to put this show as one of my all-time favorites but ended up going against it. As much as I love love loved it, some things need to be said.
So let's go on and say it...

Story 〆(・∀・＠): This show is a mystery with supernatural aspects to it. That's a no brainer.
But I love how they incorporated the superpowers into everyday society. Usually, the special person has to hide their abilities, but this show decided against that, which I ultimately loved. I also loved the mystery itself. There were so many twists and turns, which made it so hard for me to put the puzzle pieces together.
I was on the edge of my seat the entire time.
I'm not an avid mystery/investigation drama watcher. In all honesty, I watched this show to see some super-powered action as well as for Yoo Seung-ho (I'm a sucker for him). But I was delightfully surprised to find myself just itching to watch the next episode.
And as much as I can go on about everything I loved, there were a few negative things...
First is that there were so many names and faces. I struggle to remember Korean names if so many are thrown at me during a short period. I can handle the central protagonists/antagonists' names, but in mysteries, there are a lot of witnesses, suspects, and just a lot of other people. They'll come into the story then leave, so sometimes if you don't remember their name, it's difficult to feel the same shock when something surprising is revealed.
Another thing is that there were so many routes the story took. Similar to real life, there are a lot of dead ends in criminal cases. This show made sure to show it. There were so many unnecessary scenes that were added in all to throw the viewer off. While that's fine once or twice, doing it regularly makes it a bit trickier to follow.
With those two main things being said, I didn't particularly mind it. I did have to use a recap website to understand everything properly, but it never ruined my enjoyment for the show. That's why I can't bring myself to give it too low of a score.
I just had so much fun watching it! :D

Acting ｡゜(｀Д')゜｡: Oh boy here we go.
I just wanna give everyone a round of applause. *stands and claps*
There were so many emotional, mentally disturbed, and comedic characters that were involved. And pretty much every actor gave it their all. Yoo Seung-ho was flawless in my eyes and made it so easy to connect with Dong Baek. Even in the first episode, I found myself cheering him on! Lee Se-young also did fantastic in portraying the reserved Han Sun-mi. Usually, with more logical and conserved characters, it's harder to connect with them since it takes longer for them to open up. Although Se-young managed to rock it!!!
I also wanna give a special shout out to Jo Han-chul!!! My god was he amazing.
Even though he wasn't introduced in the beginning and wasn't apart of the main gang, I ended the show with Jin Jae-gyung as my favorite character. I don't wanna say why since it'll spoil too much. But know that the crazy characters.... well... their actors brought and owned it!!!

Music ヾ(⌐■_■)ノ♪: Same old situation for the music category.
The show is mystery based, so most of the background songs were just there to provide a suspenseful feeling. It worked, don't get me wrong. I genuinely felt anxious during some scenes. So the music did its job. I just didn't care much for it, which is why the score isn't as high. The ending song was interesting, though, so I'll give that credit.
But overall, this isn't a show you'd watch just for the soundtrack.

Other (ง°ل͜°)ง: Supernatural stuff. Let's talk about it!
It's so hard to discuss specific details cause then we'd be walking into the spoiler zone. And although I'd love to rant, I write reviews with people who don't like spoilers in mind. But that makes this show a bit more trickier to explain.
Dong Baek can see into people's memories. A very straight forward gift.
Yes, it was used to forward plot but not so much to where it felt forced. I really loved how it was able to fit in with everything. I did have some questions, but the show managed to end with answering most of them. I can't say what they were, but I will admit that there were one or two things that never fully got cleared up.
Thus this show didn't end with no plot holes. There were quite a few but nothing too significant.
I also liked how this show didn't rely on just the same group of police. There were different branches and roles, and the ways they interacted with each other made you question which side you're on.
Something I can really appreciate.

I think the main reason I can't add this to my favorites list is because I don't think I'd watch it again.
So much of it is a mystery, and rewatching investigation shows is just not the same the second time.
Although it can be fun to see small details you missed, this show just had a lot of story routes that led nowhere, and I don't want to have to go through them again.
But the characters and overarching plot stole my heart!
I would do anything for a second season since I'm not ready to part with it.
I 100% recommend this to anyone who likes anything related to the supernatural, mystery related things, or is just in the mood to watch something new.
It's definitely something I'll remember... let's just hope nobody wipes it ;)
Happy watching <3
