In a quirky, bustling city where the citizens are bound by social contracts that dictate their greetings, players step into the shoes of a down-on-their-luck detective whose job is simple: solve the mystery of the disappearing greetings. Each game section is filled with whimsical characters suffering from a unique greeting ailment—like the overly enthusiastic 'Hello-Phobia' or the sarcastic 'What's Up?' syndrome—players must interact with these individuals, piecing together clues and making choices that influence their relationships and the outcomes of their investigations. As the player delves deeper, they uncover a conspiracy hidden beneath the surface of what should obviously just be a lovely 'hello'!
