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?
