In a bustling urban city, a series of mysterious 'hellos' sent anonymously through text messages stirs paranoia among the inhabitants. Players assume the role of a quirky detective, tasked with uncovering the identity behind these oddly cheerful greetings. As they explore neighborhoods, engage with colorful characters, and piece together the patterns of the hellos, players must navigate humor-infused dialogue and unexpected twists. The game encourages shifts in narrative based on choices, making each playthrough unique as players attempt to unmask the person—or thing—behind the mischievous messages in a city that holds its own secrets.
