In a whimsical, chaotic city where the greetings of its inhabitants hold the power to unlock memories and secrets, players assume the role of Charlie, a down-on-their-luck greeting card writer who suddenly gains the ability to overhear every 'hello' exchanged in town. Each greeting leads to a series of humorous and bizarre mini-mysteries involving quirky characters. Players must navigate through wildly unpredictable interactions, solve peculiar puzzles rooted in people's relationships, and perhaps ditch their mundane job in the process. Will Charlie change the course of the city's fate with a single 'hello'?
