A couple of years ago(?) I watched a drama that I forgot the name of. I just remember one scene from it and if I remember correctly the main character was talking to a philosopher or psychologist and he mentioned  “Nietzsche” and the setting was in a kind of a dark room. I tried finding it on my own but I couldn’t so please if you can help me. Thank you 

Is it possibly Kirawareru Yuuki (The Courage to Be Hated) from 2017? In it, the main detective's partner/sidekick regularly consults a psychologist (in his dark-ish office) who discusses a bunch of psychological theories with him complete with on-screen graphics, etc. I don't specifically remember a mention of Nietzsche but it's not impossible (also, I see it's in your "Dropped" list).
