Brain-on sort of anime, like Apothecary Diaries

There are plenty of brain-off sort of anime, where you're just there to watch flashy fights or whatever, but I've found that I prefer thinking perhaps too deeply about shows sometimes

I want an anime that I need to be on my toes and paying attention to fully understand. I have a good memory when it comes to media, so stuff being brought back up from seasons ago is cool to me

Genre wise, I'm open minded, but I usually dislike comedy. Honestly, it's the awkward sort of cringe that's rough. Episode 5 of Dandadan was tough to get through, but I'm glad I did

Shows I've seen like this: Apothecary Diaries, Hunter x Hunter, and Frieren

Thank you in advance
