the names unfortunately don't match up. Nelloa thinks a princess called Lovena is the FL, while Haley's "actual" name is Adelaide (also a different last name, so different kingdom). it's more likely that because of Nelloa's hate parade (killing off all the other kingdoms and their princesses) caused Haley to have to run away to where she's now, effectively putting her in Bloden's path.
I think the story that woman Naloa read is the original story where Hailey is the female lead, but Hailey does not know that because she has lost her memories. Now Hailey thinks that she is transmigrated or something like that, but it's actually the original story and Naloa is the one who is transmigrated or something like that. Hailey has read the story in which Naloa had already transmigrated and was posing as the female lead.
Now that story will be different because our female lead Hailey has awoken or has remembered her past memories and is now making different decisions. The story is not going the way that Naloa wanted it to be, so now everything is totally changed.
