What came first: the KSE's original world or the world of DES?
This post contains spoilers for the whole plot, so be careful. I think some of my questions certainly will be answered in the 3rd part, but I would like to know what you think at the current point in the plot.
>!We know that the Church believes their world was created by Ireum-nim, in other words by the anonymous writers of DER from the KSE's world. KSE also once mentioned he was the one who wrote the way of obtaining Segwang Technical High School's uniform, and it actually works in real life too.!<
>!On the other hand, there are many characters who weren't mentioned in DER and still exist. Or, for example, one day in DER Segwang High just became inaccessible, but in GSGW they solved the problem wiki never knew about. And as I know, Segwang City wasn't that much described in DER though it's quite major?? There's also a problem in Segwang City being mentioned in DER even though the catastrophe occurred due to KSE being successfully summoned to their world, meaning KSE's summon must exist in the world DER describes.!<
>!Lee Heowoon said the purpose of the Cheerful Research Institute was to summon a person from parallel world without Ghost Stories. This means that worlds of KSE and DER should be parallel but they're too intertwined to not be connected in some way.!<
>!Is the world of DER some kind of major Ghost Story that appeared due to popularity among a large group of people, similar to the Ghost Story about red clothes in the subway? Does DER describe an another parallel world where KSE never became a Good Friend (if so, how would people know what's true in that world)? Is the KSE's world created by belief in a safe world and the Church trying to find out the reason for their suffering (again, how would people know about Ghost Stories then)? Can we even believe in things mentioned by KSE if his memory isn't consistent because of the effect of being a Good Friend?!<
