BE CAUTIOUS, SPOILERS AHEAD!!

Getting to the drama~
This is a great crime drama with suspense, it leads us to answers itself, here and there and everywhere. The plotline is very thoughtful, I guess the screenwriter was trying his/her best to make it more and more impressive by adding all sorts of crimes in it, prostitution, photography without permission, etc. The only problem this drama has was character development.

Story: 7.5
The plotline was very interesting, leading us to unexpected things but I guess the number of people who died was way too high than it should have been. There weren't many plot twists which is what I hated since plot twists make crime and suspense dramas like these, way more interesting. In about, 6-7 episodes, we were sure who the real killer was.
There was still a confusing thing which I didn't understand, Tae Ra saw Beom Jin and Soo Ah somewhere after which she started bullying her, what exactly was that?
Anyways, coming back, the character development was very poor, the main characters i.e. the teacher and the lawyer were very bland like how could she just reveal everything to a person when she's not even sure whether the person is a culprit or not. Alright, the lawyer is a temporary teacher but after many students find out about it and he no longer needs proof related to the school why does he have to stay there? They are not even trying to find clues, instead, they keep stumbling upon them by chance.
The spying app idea was good in my opinion. How the criminal is so good at law and he's so clever and intelligent but at the same time, he doesn't even care about being captured by the cameras? Like even if he's a psychopath, he's still intelligent and clever, he's using a girl for testimony that he was watching a movie the night Soo Ah died but he doesn't care about the cameras? He lets the balloon and letter fly, lets the child go away, he's such a dumb psychopath yet he's so clever. WHAT???
I didn't find Soo Ah any special, is she so beautiful, a goddess? Like, how come almost all the male characters in this drama want her?? Flirting with Beom Jin, having secrets with Gi Hoon, working as a prostitute, what more? Like, yes she was really pitiful after hearing her story, but it doesn't mean she can make bad decisions and not be blamed for it. She brought this upon herself and I feel like she was the most hateful character in this drama.
Well, no offense to those who loved it but this was really poor.

Acting/Cast: 9.0
The acting was quite satisfactory overall.
⨠Yoon Kyun Sang as Ki Kang Jae and Lawyer Ki, his character was ok but his acting was really nice.
⨠Guem Sae Rok as Ha So Hyun, I didn't really like her character, but she was good at her acting as well.
⨠Lee Jun Young as Yoo Beom Jin, being a great fan of Lee Jun Young, I felt a bit bad for his character in his drama, it was so dumb to create such a debatable character. Anyways, his acting as the cold killer was really nice.
⨠Choi Hyun Hwa as Prosecutor Cha, her acting was really nice as well, although her character was a bit confusing, why did she hate Lawyer Ki so much? Nobody knows. MYSTERY!!
⨠ Choi Kyu Jin as Lee Ki Hoon, his character was one of the few I understood in the drama, good acting anyways.
⨠Han So Eun as Han Tae Ra, I didn't like her acting very much, her panic scenes, sad scenes, etc. all seemed so fake.
⨠Kim Myung Ji as Na Ye Ri, I really hated her character and so I would say the actress played it well.

Music: 10.0
I really liked the rap regardless.

Rewatch Value: 9.0

Overall: 9.0

Hope it wasn't boring.
Still, you could just go ahead and try this drama as it was interesting with no doubt..
Thanks for reading.
Lots of love <3
