In a bustling metropolis where greetings hold more weight than mere words, players assume the role of Kai, a sarcastic introvert with a knack for deciphering social cues. After receiving a mysterious box filled with unclaimed 'hellos' (messages, greetings, and even failed attempts at small talk), Kai embarks on a quest to unravel the stories behind them. Each greeting leads to unique encounters with a cast of quirky characters, from an eccentric poet to a conspiracy theorist lost in the power of hello. Through conversations, puzzles, and choices, players must piece together the importance of these seemingly trivial greetings and how they’re entwined with the characters’ fates.
