lurker's comment on Chapter: Omniscient Reader’s Viewpoint (Web Novel KR) - Chapter 354: – Beyond Good and Evil (4)

I dont get whats the big deal about it.
Whats the big deal about it? Its not like the real world and the story can separate anyway? KDJ HSY cant just quit this story and move back into the real world. 
Plus, with the way things are, they might very well be real people not just characters of a story. When the story started, people like Hyunsung, Lim Namwoon didnt fall into the train compartment from somewhere else. Meaning they were already in the train before the scenarios started. This means they are real people.
The author of this book might be something like the true g** of this world (like the thing that KDJ is the apostle of) and he/she/it just supported his apostel by preparing him for the future through this story.
The fourth wall might be link between KDJ and whatever the thing that KDJ is the apostle of.
