Solo leveling: I am you, You are me... Just the exact opposite (Au)

Hello! Author here. I currently do not know how to make the synopsis of the fanfic so I'll just put a part of the story.

Hi! I'm Saul. I am die-hard fan of the novel solo leveling. I always had regarded it the best I had read.
I was reading a manwha when I saw a silhouete of Sung jin-woo on the character. "Haha, time to go back to my personaly favorite novel, huh? Might as well read it incase I forgot anything about it." I mumbled, smiling with nostalgia.
I read the novel again stopping at chapter 200 as my mom called me down stairs. "Saul! Get your lazy ass out your room and go buy some milk! We ran out of it."
"Ok. Okay! Just stop shouting, mom." I said as I open my door and head down stairs. "Bye mom!" I shout as I leave the house.
Little did I know it was my final good bye. As I was admiring the red spider lily photo on my screen, I heard a honk and I looked at the direction it came from.
*Honk*
I saw a truck carrying chickens a meter infront of me honked and I was shocked.
I couldn't move, my body refused to listen as I feel freezing aura coming from the truck.
'Ah! my legs are stuck they won't listen to me! What is this pressure that's forcing me into an immovable state?!' I thought.
"Cut!!! Cut! Okay thats enough. Now, interested? Read the rest of the chapters in the table of contents. Not here!"

Although the title suggests that this is a solo leveling fan-fic this might end up in other stories like TBATE and they will always be siblings. Welp what can I do but just continue this story untill it may or may not progress lik what I have said.
