In a world where communication has become a twisted game, you play as Alex, a former linguist turned private investigator who wakes up in a city where every greeting uttered changes the game's reality. Each morning, you receive mysterious 'hellos' in envelopes that are linked to bizarre events happening in the city. As you uncover the origins of these hellos, you'll navigate through shadowy underground societies, encounter eccentric characters, and piece together a conspiracy that alters language and reality itself. Your choices affect not just the clues you gather, but also how the city and its inhabitants react to you. The clock is ticking, and the next hello might just be your last.
