In 'Whose Hello?', you play as an overworked barista in a hipster café who stumbles upon a mysterious notebook. Each page contains a unique greeting sent by various patrons, each with their own quirky backstory and hidden agendas. As you dig deeper, you find that these seemingly innocent greetings are linked to a series of bizarre events in the café, leading to the disappearance of a local influencer. Your task is to piece together clues from the notebook, navigate through the eclectic personalities of the customers, and ultimately discover the truth behind the chaos—all while keeping your caffeine levels up and your sanity in check. Each decision you make will lead to unexpected and often hilarious outcomes.
