In a world where greetings have mysterious supernatural powers, players assume the role of Alex, a snarky barista who inadvertently inherits a sentient book of hellos after an encounter with a bizarre customer. Each hello leads to different scenarios, introducing strange characters who hold the key to unraveling the mystery behind a long-lost village and its whimsical inhabitants. As players navigate through unexpected twists and interactive dialogues, they must decipher the true meaning of the hellos, form alliances, and ultimately decide whether to protect this world or let it vanish forever.
