Whose Hellos Are These, Anyway?

In a bustling, quirky town where everyone knows each other, you've just received a mysterious box filled with postcards from unknown senders, all saying a simple 'Hello.' Each postcard contains peculiar clues about the residents of this town, leading you to question their identities and motives. As the new outsider, you must navigate social interactions, gather intel, and uncover the truth behind these strange greetings. Engage in hilarious conversations, form alliances, or throw your suspicions onto others, but be careful: trust is scarce, and misdirection is the name of the game. Will you reveal the secret behind the postcards before your own identity is uncovered?
