The Novel's Extra Nobody

This is... so trippy... Like... Hmmm... How do I explain this? I am now inside the novel, where the main protagonist is inside his own novel. Does that even make sense? After reading [The Novel's Extra] by Jee Gab Song over and over again from the novel, manhwa adaptation, and back, I am now in this situation where I have to live throughout the story as another extra. Sigh... and... daym... What is Chae Nayun doing there? *** Author's Reminders. This is a fanfic based on TNE by Jee Gab Song. The story will start diverging after Yeonha's incident a lot. Expect new devils, stronger Djinns, stronger villains, and lots of struggles from fighting scenes. MC will start weak and grow into an OP character. MC might seem happy-go-lucky, but give him a chance. Also, MC can often be cringe. Also thank you for reading. Updates are every 11 hours.
