I don't think my question would be answered anytime soon, if at all, during the run of the manhwa, but this chapter makes me wonder: why would the novel author deliberately write their story like that? It's way too creepy to have your fanbase divided into a team which reads this as a broken hero trying his best to find solace in companions and saving the world, and the team that recognises the unreliability of the narrator, thus reading a dark tale about an already tragic hero wrapped in an even more tragic story of everyone he trusted being potentially total liars and him being none the wiser.
I mean, this information alone is a game changer. Were they going to write a sequel? It sure doesn't look like they hinted to it in the original novel. This kind of novel is not often left for reader interpretation of events, so if they weren't going to do something about it, then I don't see why go to all the trouble to create and maintain this specific gimmick. I went back to the first chapter too, and it reminded me that it felt odd the first time around seeing the author specifically addressed as "mysterious". Makes me wonder if there's a link there. Who IS the author anyways? Transmigrator and the like? Or just an unrelated party?
I feel as if I'm thinking too much about this, which is making me feel like just letting this particular thought die.
