In a world where every character's greeting holds the key to their true identity, players take on the role of an amnesiac hero navigating a bustling city filled with quirky residents. Each character they encounter uses unique phrases and tones when saying 'hello,' which can unlock hidden backstories, secret quests, or even betrayals. As players piece together the identities behind the greetings, they must make choices that influence their relationships and shape the future of the city. Balancing humor, friendship, and intrigue, the game offers multiple endings based on the connections formed and the secrets unraveled.
