What if some of my favourite kdrama psychopaths met each other:
Initial reaction: put on the poker face > turn up the charm > look as harmless as possible > use favourite skill, aka manipulation > smile > discreetly reach for a weapon
After initial reaction:
Honestly, they would probably vibe for a bit first (except for Kim Gwang-il, I feel like nobody would like him).
Seo In-woo is probably the one with the least problems here - he is neither delusional, hallucinatory, amnesiac, impulsive nor plain crazy (arguably) - he is calculative and has the resorces to cover up his crimes effortlessly. He would probably not be the first to strike, he'd bide his time, maybe let the others take each other out first.
Seo Moon-jo I feel like wouldn't engage as much either because he feels almost supernaturally creepy when compared to these other people. Like, he is the kind to stand smiling in a corner while staring and eating questionable raw meat from a plastic bin. He would probably set his eyes on Jung Ba-reum as a target of his manipulation though.
Mo Tae-gu is kind of unstable sometimes with his hallucinations and resulting anxiety, so he is a wildcard here. He is probably still the strongest of the bunch - kettlebells and all. He might get along with Seo In-woo on a surface level, but they would only pretend to be cordial. He is definitely one of the more violent ones.
Kim Gwang-il... As I said, this entitled unserious bastard would be hated quite quckly due to his behaviour and unpolished nature. I can't see a single other person from this list who might want to spend time with him.
Jung Sun-ah would be underestimated by at least a few of the men here (*cough* Seo In-woo, Mo Tae-gu and Kim Gwang-il) but she would use that to her advantage. She is more driven by revenge, but she is also power-hungry, so I think she'd try to ally up with the more sane ones, and then waste no time stabbing them in the back afterwards.
Jung Ba-reum would be a target both because he is a cop but also because he looks the most innocent, and he is the one with the least intentions when it comes to killing. He would be mostly on the defensive side.
What if a fight breaks out?
Kim Gwang-il would go first, either by Sun-ah when he tries to mess with her or by Moon-jo getting tired of his crass and artless bullshit. Of course, Mo Tae-gu and In-woo might bash him in first if they get too annoyed.
Characters and dramas:
Seo In-woo from Psychopath Diary (2019), Seo Moon-jo from Strangers From Hell (2019), Mo Tae-gu from Voice (2017), Kim Gwang-il from V.I.P. (2017), Jung Sun-ah from The Devil Judge (2021), Jung Ba-reum from Mouse (2021)
Also, bonus mention to my favourite fake psychopathic serial killer Yook Dong-sik from Psychopath Diary - he would probably survive against all of these other characters just by confusing the living heck out of them with his sheer stupidity (endearing).
