I don't know what made me think this was going to be a spooky season drama about cops that hunt down ghosts that cause chaos on the subway, but I think it rooted from confusing this drama with the one I watch before - Bring It On, Ghost. Both great dramas, but both completely different. I think I found this one solely because The Rose's Woosung sang on this drama's OST, so I had to watch it in order to jam out at the end of every ep.

The drama started off with a simple mission; the subway team needed to find the Grasshoppers (who were a team of pickpockets that have never been seen) and the metro team was in charge of finding the Subway Killer (serial killer to lured individuals by stealing their wallets, contacting them to get their wallets, strangle them to death, and then hide their bodies under the seat cushions in the subway). We have the chief of the subway team - Go Ji Suk, a promising young metro officer who quit the force to solve petty crimes to help pay and take care of his mother who was diagnosed with alzheimers; and Yoo Ryung, a fiery officer trying to find a way into one of the crime unit teams to use their resources to help further the search of her twin sister who disappeared 2 years ago (and a possible victim of the Subway Killer.) Yoo Ryung finds herself joining the Subway Team as Go Ji Suk's partner, but are always at each other's throats due to their conflicting ideals.

I did love the relationship between the two mains, but I felt like Ji Suk trusted too easily and Yoo Ryung was extremely selfish and secretive. Once we find out why it is, it makes sense why she did what she did, but it was painful to watch the process of it all. I must say though, once everything comes together and Ji Suk connected all the dots, there is a touching scene of him sticking up for her. It was my favorite scene in the whole drama.

Overall, I really enjoyed watching this drama. It surprised me how light and comedic is was in the beginning, and how dark it got whenever they got a clue about the Subway Killer. The drama only got better and better as it went on. The only thing that I wasn't a fan of, was that even though the drama took a dark turn, the relationship between Ji Suk and Yoo Ryung was very...PG...or really G rated throughout the drama. They did have some moments, but if you are wanting to watch a romance drama, it wasn't very satisfying. Yes, we get the happily ever after between the mains, but instead of a huge love gesture at the end...it was more like, the mains finally agreed to go out. It makes sense why it ended the way it did (given Yoo Ryung and all the stuff she needed to figure out before thinking about a romance), but I am very content with how Ji Suk came through, once he figured out Yoo Ryung and why she did what she did in the past. I wasn't in love with the characters in this drama (they were both extreme people on opposite sides,) but I did enjoy how the writer made them come together with both unexpected and tragic backstories, that were completely different, but somehow, the experiences they both went through made them into similar people.

Also, I was in love with how dark the drama was as well as it kept you guessing on who the killer was. Once you think you know, they throw in another curve ball. It was a little messy at times and there seemed to be a few plot holes, but overall, I was very entertained and I loved how everything made sense at the end. I almost want to rewatch this whole drama again, to see if I could figure out from the get go, just by the obvious clues they do give you, that I missed the first time, who the killer was. PS, I thought it was a little worth mentioning, but even though he messed up one time and I apologize for thinking you were the killer (in the beginning), Kim Woo Hyuk was kind of bae. After no one wanted to help Yoo Ryung find her missing sister, he decided to break the rules in order to help her. Unfortunately, Yoo Ryung had already made up her mind on him 2 years prior when his partner, Ha Ma Ri, wouldn't help her with her sister's disappearance. And speaking of Ha Ma Ri (as well as looking at all the comments and reviews, who all seem to have a similar view point), I am not sure if it is all the roles that she plays, but I am not a fan of any of Jung Yoo Jin's characters. She always plays this second lead (from the dramas I have seen) who somehow believes she always has the upper ground and does not let anyone forget it. In this drama, she was a great detective, but had had zero empathy towards people and she followed EVERYTHING by the book in order to impress her mother, the director. Unfortunately, her mother always seemed to admire great cops who showed empathy towards people - Ji Suk when he decided to take a demotion in the beginning of his prime in order to be there for his mother and Yoo Ryung, who decided in the middle of the Grasshopper investigation (if they followed, they could have caught them) to save a baker's son who had been kidnapped. Plus, Ha Ma Ri, after 2 years, still was hung up on Ji Suk and made missions personal when she saw his relationship with Yoo Ryung. I think that was one of the better scenes, when Yoo Ryung and Ji Suk switched partners during an investigation and we saw how Yoo Ryung effected Ji Suk in terms of what truly mattered during an investigation. He noticed it and so did Ha Ma Ri, and it was a turning point fo everyone.
