Can you guys recommend me any good psychological stories (no gl, BL or sl)?

Have read Bastard yet?

Koko wa ima kara rinri desu

It's about philopophy mostly, an ethic teacher teaching students about it. It changed my perspective of things a lot

I've already read that

No

I think it's one of the best psychological stories I have read in years. I hope you like it and I hope you give it a try. https://www.mangago.me/read-manga/bastard_hwang_youngchan/

I'll read it, thanks!

Anytime!
