!!MAJOR SPOILERS!! WATCH FIRST

This drama is so good! The plot twists, everytime I think I know the plot, they hit with the are you sure? then it changes woah!!

At the start it's kinda confusing cause I don't know and literally can't remember for the life of me who's who but it's always like that at the beginning still this one had too many people!!

I was so confused with Jae hoon and Sung Yo Han, swear those two were the same person?!? I thought I got his name wrong this entire time but actually it's not even him it's BA REUM!!!

Ko Moo Chi was my fav since day 1 like how are u gonna try to kill someone and when they try to do it themselves you scold them as if they're your child??? talking about some 'come down from there now', 'I won't shoot you I was just playing', 'you're too pretty for jail and you know they're perverts there so...'? and this is ep 1 don't get me started on the pettiness, he really kicked his seniors chair cause he was frustrated, you weren't wrong but please don't throw a tantrum in the middle of a police station?? all fun and games but stop promising people you're going to kill for them!!

Moo Chi and Choi Hong Joo hilarious at the begining, they're a duo but not really because it's just for mutual benefits.

Bong Yi and her grandma are such an amazing duo everytime they're on screen I end up laughing though it's kinda sad wish they were nicer to each other, can't believe Bong Yi decided to blame her and called her cause she can't walk in the rain!! First of all Ba Reum is meant to be walking you still (I think) and second let's get a therapist and deal with our trauma because my grandma won't be there for me forever how about that huh?? PLUS she loves to blame everyone. To be honest Bong Yi trauma is 100% valid and her not being able to cross the bridge is fine but please don't blame everyone around you.

I was genuinely convinced that Ba Reum was a psychopath from episode 1 because of his interaction with the head hunter and slowly I was piecing it together like when Daniel said that the gene is dormant and gets awaken after the first kill I thought maybe that's why Ba Reum is so nice, sweet and sensitive?? Or when Yo Han mentions about the other child who is a monster that I physically erased from my memory how could I forget the mom met another mother at Daniels clinic!! But I kept doubting myself and still ended up liking him though so the end of episode 4 I was so shocked!! I thought it was Yo Han then.. its all fake!? And Ba Reum was super cool and brave instead. After comes episode 6 where Ba Reum and Yo Han are both dying and having this prolonged eye contact for whatever fucking reason, it just makes me like him but also be more suspicious of Ba Reum then when he killed the bird I wasn't even shocked (kinda wish I was tho would make it more interesting) but was instead super confused was I right? are you showing your true self cause you're pissed or is it a change that happened now?? But Thy tricked me and said it's cause of the injury!! but I WAS FUCKING RIGHT, it's too late though I've already grown to love this psycho <3 was really routing for him in his imaginary fights with Yo Han lol. Didn't want him as a psychopath watching him talk about the hiking murder actually creep me the fuck out bring back sensitive Ba Reum, I still have mixed feeling after everything cause psychopathic Ba Reum is kind of... but sensitive Ba Reum is also so I really don't know!!

Ba Reum psychopathic 'twin-telepathy' connection is dumb af that's literally impossible like you can sense something maybe if you're near or hold a convo/eye contact with someone and be like wait maybe we're similar, I accept that BUT not just a straight up your not a psychopath, your not a psychopath, you... are not a psychopath but YOU def a psychopath, cries wtf?!?

Iwas panicking when he was having 'Yo Han's' memories literally I was like; Why is he having memories of young Yo Han aka Jae Hoon when it's not his?!?! Are u literally mentally connected omg please don't let this show go down hill it was going so well!! Are him and Yo Han like spiritually connected cause Ba Reum felt hurt when seeing Hong Joo. Glad that wasn't it cause the show would've downgraded.

When Seo Joon transplanting his Yo Han's brain into Ba Reum because of Hong Joo, I wanted to slap her because I thouh it was because of Yo Han, now knowing the truth I'm so glad she did.

Moo Chi anger during the live in episode 5 is truly heartbreaking got me sobbing while watching it... then what they did to his brother why!!!

I feel a bad for Yo Han cause a some of students tried to beat him to death just cause of his 'father', all of this pain because of his mom poor boy.

Bong yi with Suseong serial murder case saying that Ba Reum will find the survivor then when he says that's hard, her and Koo Dong Goo give him puppy dog eyes, adorable but cmon are u a pushover or just a softie towards Bong Yi, Ba Reum lmao. Bong Yi is so unlucky she can't just live her life!! then Ba Reum being the true killer all along omg Bong Yi run before it's too late!!!

There were some weird transition or scene cuts throughout the show at one point Bong yi was in the rain with her hood all the way down then at a different angle she wasn't it was a little messy but just some scenes and I wished they stated things properly too cause even after getting the answer it still left me somewhat confused, this is because instead of giving us an investigative storyline we got given one with holes or a manipulated view where we have to throw that entire view away once the true answer given. They use science and scientific terms though it's scientifically incorrect which as someone with degree not just in science but forensic science it annoyed me at points it even got unrealistic where I just wanted to yell that's not how the world works. Another thing you shouldn't look too deeply in is certain logistics like why two guards who are protecting someone both leave their posts unattended it's stupid.

All the characters had dark pasts to try and justify why they acted a certain way which to be honest was a little too much and at times just wished they'd stop. Though I enjoyed this drama it was cause of the actors story and scenery as well as the emotions portrayed that made me fall for this because the plot you could easily guess it and at the end they gave a cliche bad guy turned good one which was done beautifully but also wish I could have gone a different way.

!!My favourite Moo Chi quotes!!

"Come down from there now!" and "I won't shoot you I was just playing" need context with these but why is he saying this when he is a detective!? he need to be fired but also don't lol.

"I heard your parents waited 10 years to have you. I bet they were thrilled without even knowing how spoiled you'd turn out to be" it's limited edition okay I would want it back too even if its an umbrella.

"No, I found you uncomfortable" (saying it to Choi as she wants to work together after the whole Yo Han thing) damn straight faced and all, I get it but no hesitation whatsoever lmao

"I dont like that jerk either" Lol after yelling at Nepo he moves straight to Detective Lee leave them alone u deserved to sit in that cell and use your leftover braincells to think over all the stupid shit you do as you try to get yourself imprisoned!!

The entire I got mugged speech and the other officers looking a him like *side eye* hilarious.

"I should've caught and killed Kang Duk Soo myself. You have no idea how bitter I am that someone beat me to it" HOW CAN YOU SAY THAT AS A DETECTIVE?!?! How this man still has a job is truly a miracle, make sure u pray to God and your brother cause he def did some amazing work for you to be living while being this lucky.

Though this is an absolute masterpiece it's one with flaws, it's made to make you think and I will be talking about this for months to anyone who wants to discuss this. the possibility of finding psychopaths before they are born or the punishment and irony of the show I have so many different views of this that I'd love to rewatch and discuss with someone.
