Set in a quirky interdimensional café, players assume the role of an unexpected barista who serves a wildly diverse clientele of fantastical beings—from time-displaced knights to talking animals—who each arrive with unique mysteries and bizarre greetings. The player must interact with these customers, decoding their convoluted hellos to uncover clues about their pasts, solve comic puzzles, and ultimately figure out why all of them are mysteriously linked. Each choice influences the unfolding narrative, leading to multiple endings based on the connections made and the hellos interpreted.
