2. It could be that the way Huimin went back to the “novel” was that because he read their original world (The novel) causing him to go back to there, but not as the Huimin Seo of the novel, but the Huimin Seo he wanted to be. No trauma, no problems in life, just pure and innocent, back to when he knew nothing.
Also take note that the person who made him read silence was Iheon. You can see from the silhouette back in Chapter 1, it was Iheon who gave the book. But why? That is a theory I can't make.

He maybe made him read it so that in case they return to the world, Huimin will remember. It would be easier to communicate if Huimin knows what happens next. But Huimin kept denying he knew something, so Iheon probably thought it didn't work.
It still helped them, since Huimin was less traumatized when he came back to the novel world, thinking it was a fantasy.

Maybe to get him back to the novel world? Since Iheon went to the “parallel” world and sees the novel maybe he realizes at some point that he isn’t a character from a book, it’s just his life was recorded as a novel and he tries to go back with Huimin?? Or maybe this is just transmigration??? I’m so confused it’s killing me
1. Silence (novel) is the actual original world, the world they're in right now is Huimins “Made up” world, Novel Huimin was so traumatized and unstable he drew pictures of what he would've wanted to happen, what life he would've wanted to live and it did happen. So their world is the one made up, not the other way around.
