Set in the bustling city of Aetherium, players assume the role of Arkai, an eccentric private detective with a knack for uncovering peculiar secrets. Arkai stumbles upon a series of bizarre 'hello' notes that mysteriously appear around town, each leading to a different person kissed by chaos and intrigue. As you interact with a quirky cast of characters—from a conspiracy theorist who believes these hellos are coded messages from aliens to a shy barista with a passion for poetry—you must piece together the underlying connection between these hellos and an impending city-wide festival. Unravel the threads of their lives while making choices that shape the narrative, leading to multiple endings that hinge on your ingenuity and wit. Can you crack the case before the festival goes off the rails, or will you end up lost in the 'hello' maze?
