In "Whose Hello Are These, Anyway?", you play as a disgruntled librarian named Finn who stumbles upon an ancient book that grants the ability to hear greetings from the past. But these aren't just any greetings; they come from famous historical figures, each with personal messages and unresolved issues. As Finn navigates through these bizarre interactions, he must piece together clues about why these figures are contacting him, solving both puzzles and their quirky dilemmas. Along the way, hilarity ensues as Finn accidentally triggers ridiculous events that reshape history, leading to comedic outcomes and a race against time to return everything to normal before the library magically disappears forever.
