maybe this is a novel and she's inserted into the story and she likes the Five Guys in the story and she wants to save all of them from a horrible ending and that's why she's there and those Grandpa's made it possible for her to enter the story
Is the grandpa's actually their older selves from before? It's weird to explain but I believe this daddy is a younger version of one of the grandpa's. Is she created not born? hmm this is all my brain đ§ is thinking so far .
