Each hello leads you to unique characters—some are helpful, while others are downright bizarre. As you unravel the mystery behind the disappearing 'hellos,' you must navigate through the eccentric underbelly of the city, engaging in witty dialogue, making peculiar choices, and gathering clues to uncover an underground society that communicates solely through greetings.
