In a near-future city where AI has taken over most social interactions, a peculiar glitch springs open a portal that allows people to swap hellos - literally. Players assume the role of eccentric characters in an underground club where custom greetings have become the hottest commodity. You must deduce which hellos belong to whom, gather clues from the rival greet-slingers, and navigate alliances and betrayals in a city where a misplaced greeting could lead to scandal or fame. Use a combination of wit, charm, and deduction to uncover the ultimate secret of the 'Hello Exchange' and find out whose hellos have the power to change your destiny.
