Highly recommend Save Me, Pet Shop of Horrors, About Death, Diamond Dust and Bastard. The others are great as well but I'd start with those ones (mainly Diamond Dust or About Death) and save An Uncomfortable Truth and unhinged for last because I feel like they were weaker in the psychological department compared to the other amazing works.

Until chapter 22 it is some boring BUT after that is quite interesting.
(Sorry Killing Stalking is the best)
my life is decreasing by the second so I'd love if you guys could recommend me some psychological manga. Idk something about them just... hits better? Ya know? And i've read killing stalking so many times and it never gets old. But please, help a sad old worm out and give me the good stuff if you have any. I'd just love to have a buddy to talk to because my darkest interests are kept here where people like you guys understand me. so don't be afraid to hmu k? *fist bump* k i go now. ╥﹏╥
