Care to spoil?! How is he a psychopath? Σ(っ°Д °;)っ
In the novel we get to see his P.O.V. He sees everything like a system and dehumanizes others. He also lacks empathy, like your average person with antisocial personality disorder. He'll become extremely obsessed with mc but he'll be annoyed with his attraction towards him since mc for him is like a "stain" to his perfect "system". He'll purposely save mc from certain situations so that he can win him over. It's been a while since i read it so I can't really remember, but there are plenty more morally ambiguous situation that will give you the chills in the story. Go and read the comments on novel updates to get more spoilers.
Thanks for the summary! He seems like a well layered character(⌒▽⌒) Hopefully lacking empathy doesn't mean toxic.
Based on the novel, he unfortunately is. There's a lot of 'coercive' moments.
It's not that he lacks empathy. Mc is emotionally numb because he suffers from trauma. He dissociates himself from any situation that could possibly make him feel any negative emotion, he copes through avoidance. Also he lives purposelessly and this is the result of his trauma as well, even if he says that's it's by choice.
As for the attorney, he's very unsettling. I don't really like the way he approached mc but i don't think he's the reason his friend committed suicide. It was unbelievably naive of mc to follow him in his car.
Edit SPOILERR:
I TAKE EVERYTHING BACK about the attorney. He's a straight up psychopath. He's 100% the reason mc's friend most likely killed himself. The unsettling feeling checks out Jesus. Poor mc isn't going to be a smart protagonist either, considering he followed this trash in his car.
