I just find out that this have a novel damn

I can't find the any translated novel, so I only read the spoiler through namuwiki, which always being petty and only wrote a little bit and It's like a wikipedia. I read the MC's information, and as far as I know there's no mention of him get married or having a relationship with anyone, because at the page about the future him is all about him working for that company in Daesan as the secretary or something.

There's no spoiler about it in namuwiki ╥﹏╥ but I think they're going to be okay since there's no "Deceased" written in the page lol
The brother is actually very intelligent, despite MC keep the secret about whatever he was doing, the brother will catch on. He can guess, so he is working with the rest of his school to defend Daesan and the school itself, using his brain lol

I still don't understand tho, even after reading the novel-update spoiler. Why is he keep returning? And why the flute the max level him (doesn't know what to call it), the one that become a "demon" or something, is exist in the same time as the current him? Why FL reincarnated inside that novel. Why?????? I keep reading even though I don't understand.

Spoiler
He's returning because the strict order abandoned that world, but the world didn't want to just lay down and die, so the strict order slapped the band-aid know as tez on it to keep it alive. As long as tez is alive the world is too, even though that same world tries to kill him as an anomaly.
The demon him is named Reed and he's what tez becomes on loop 100 after falling into rage and despair upon learning the strict order abandoned the world already and left him to deal with the consequences of the strict orders choices. Reed can exist in the same timeline because when he falls to corruption he was able to spend a few decades in a sort of abyss that he wasn't sealed in to grow stronger in magic and demonic power instead of divine power. Once he was strong enough he could rip open the dimensions/timelines in order to find and kill himself before he awakens the rebirth ability initially, but like we see it the beginning of this season, it doesn't work.
The Fl Ally didn't reincarnate into the novel, she was transmigrated into it pretty much at random. Maybe it was because she bought the full package before she died that she got assigned the harder world, but thats not really ever brought up.
Any other questions? I haven't finished the novel, but I'm on like chapter 190, so i know a decent bit.

Reading up to chapter 2, omg that was horrible. I can tell the stench is bad ╥﹏╥ my parents have rented house (room per room, mostly for college/university student), we also have a single house to rent and it's around 3x3m² (I'mnot sure but it's not that big). The one who live in the single house died during covid, we discovered it late + he is not very "clean" to bgin with, it's filled with all of his garbage, a lot of cockroach and rat carcass (when cleaning after he died, we even found cat carcass ╥﹏╥). Since he live that dirty, the smell outside his house was considered "normal" for people around, though my parents scolded him a lot, he just don't care. My parents pitied him so they didn't bother anymore as long as he paid the rent, sometimes he even added more money on it, so we’re okay. Since he died in the upper floor, the stench from the outside was no different from the usual stench. But when you go upstair and opened the door .... ugh it's smell so bad. That was my first time smelling something like that, I barely can eat for a week. And it's coming from a single corpse, on a room that was not that big. Imagine smelling that in a whole city
This better comeback asap before I lose my sanity. I lost count on how much I finished re-reading this. Please save me a least
