Because you started it? You made a theory about the original Canaria... who was written by her author to be a specific, limited, villain character who got her comeuppance so the true heroine could get together with the protagonist. In a real world, yes, there could easily have been complexities to her character that no one else was aware of. But... she wasn't a real character. There never was a true "original" Canaria. She was a work of fiction, a literary contrivance. A collection of specific tropes used solely to interfere with the "destined" lovers getting together. I spoke up because it seemed like you'd forgotten that the "original" was a work of fiction, and were treating it more like a time-travel story, where the original Canaria was a real person who could have had unknown motivations and been misunderstood. I was attempting to remind you that, as interesting and tragic as that would have been, we already knew it wasn't the case, because our heroine has read the novel and knows what sort of person the character Canaria truly was.
Regarding the existence of the world, I feel you're still not getting what I'm saying. In the original novel, that our heroine read before she died and was reborn here, there WAS nothing outside of what was written. It's a NOVEL. The only content in it is what the author has put there. There is no universe or world involved. There is nothing outside what the author has written. That's the case with all books, manga, movies, tv shows, anime, stories, and any other fictional medium: the only content that exists is what the author has written, and there is nothing else outside of that.
THAT, has no bearing whatsoever on the world our Canaria is now living in. She isn't inside the book, she's in an actual world that is basically a "what if this story were real" sort of thing. For her, yes, there is plenty that can and does exist outside of what the novel covered. We've SEEN that: she had no idea the prince's palace and household were being robbed by greedy employees until said something to make her suspicious. For her, yes, this is a real world where a great many things may exist outside of what the novel covered.
