Who Said Hello?

In a bustling city where every citizen is a potential spy, you are an undercover detective assigned to investigate a peculiar series of events surrounding a simple greeting: 'hello.' As you traverse various locales—from quirky cafes to dimly lit alleys—you encounter a diverse cast of characters, each hiding secrets of their own. Use your wit and charm to piece together clues, engage in dialogue trees that reflect your choices, and ultimately determine the truth behind the mysterious saying. But remember, in a world where trust is scarce, who said 'hello' might not be who you think it is!
