In 'Who Said Hello?', you step into the shoes of a skeptical detective in a quirky, sprawling city where every character holds a secret. While following a series of bizarre greetings that have disrupted the usual monotony of life (like public announcements of love, competition between rival coffee shops, and a slew of mysterious note exchanges), you uncover a deeper conspiracy tied to the city's forgotten legends. As you navigate through humorous dialogues and unexpected twists, your choices shape not just the outcome, but the very identity of the characters you meet. Will you solve the enigma of the puzzling greetings before it spirals out of control?
