Set in the quirky town of Mirthvale, where every resident has a peculiar 'hello'—an eccentric greeting that reflects their personality. Players assume the role of a disgraced ex-detective who has returned to Mirthvale with a mission: to unravel a conspiracy involving an unknown mastermind manipulating the town's greetings to gain control over its inhabitants. As players navigate through a series of comedic and dramatic encounters, they must gather clues, solve puzzles, and interact with a motley crew of townsfolk, each with their own secrets. The catch? The solution to the mystery lies not only in the hellos themselves but in the relationships between the characters, which evolve based on players' choices, ultimately affecting the fate of Mirthvale.
