Whose Hello is it, Anyway?

In a vibrant city filled with peculiar characters and quirky situations, you play as an amnesiac detective with an uncanny knack for questioning the mundane. Your journey kicks off when you receive a mysterious voicemail containing only a friendly greeting that wasn't meant for you. Each chapter sees you unraveling the connections of the greeting to different inhabitants of the city—from an overly charismatic librarian with a secret, to an eccentric street performer who insists on performing Shakespearean soliloquies in the middle of the street. Your choices determine not only the resolution of each quirky scenario but also influence your detective’s personality and relationships with the city's inhabitants. Can you piece together the puzzle of the voice that said 'hello'?
