In a world where greetings are stolen and identities are shrouded in mystery, players assume the role of a sarcastic detective in a bustling city where people communicate through coded expressions rather than words. As you navigate various settings—from quirky cafes to secret underground clubs—you must interact with a cast of eccentric characters. Each character has their own greeting style, and it's your job to deduce who is a friend and who is a foe. Gather clues, make witty banter, and decipher the labyrinth of social cues to uncover a shocking conspiracy about the theft of the 'Perfect Hello'. Will you befriend the allies hiding in plain sight or fall victim to the charm of a master deceiver?
