In a bustling metropolis where greetings hold mysterious powers, players assume the role of a rookie detective, tasked with unraveling the odd phenomenon of 'misdelivered hellos.' Each hello has a different effect on its recipient, from inspiring unexpected bursts of creativity to instigating spontaneous dance parties. As players navigate through various quirky characters—from a forgetful librarian to an eccentric street artist—they must piece together the origins of these hellos and a nefarious plot to control them. Choices made during conversations and actions affect relationships and the ultimate resolution of the mystery. Time is of the essence as a countdown looms on the city’s annual 'Day of Hellos,' where the fate of greetings will be decided once and for all.
