Whose Hellos Are These, Anyway?

You awaken in a mysterious library filled with the echoes of countless voices. Each voice belongs to a different character, all of whom are trying to converse, but in a chaotic, nonsensical manner. You are tasked with uncovering the source of this disarray—a mystery woven through the tales of the book characters both familiar and strange. As you navigate through various chapters of their stories, you uncover secrets and face decisions that will impact the narratives. Can you untangle the threads of chaos and help these characters find their rightful greetings, or will the library become your eternal prison of awkward hellos?
