Idk what to put here

I will start reading it next week, as can't right now, so i wanted to ask a few things to know what i'm getting into.

Is it recommended to read it slowly to get more of the details or foreshadowings? Because 539 chapters is a lot, and i've seen some people say the first 100 chapters are really slow, so it might bore me out.

Would it be a problem for me to look for an analisys? My media literacy isn't the greatest, so I might not catch all the symbolisms or the deep writing at first.

But despite that, i'm really curious of how a gambling manga will become peak fiction, because my only reference is kakegurui, so i don't know what to expect.
