But

Personally I don't think so, because before Melissa she tried to change the story and it didn't work but Melissa already successfully changed it. My theory is that Yuri was the only one with awareness about loop, but because she is actually a character from the book, she cannot change the story. But Melissa (or more like the soul in body of Melissa) isn't actually from the book so that world can't force her to follow the story. And since it's already changed i think either the book changed too and this is the new story now or more likely the loop itself will broke at the end of the story and this reality will not be bound to the book anymore.
