In a bustling, futuristic metropolis, you play as an undercover agent investigating a strange phenomenon: people have begun saying hello in increasingly bizarre and obscure languages, creating chaos in the city's social fabric. Each encounter involves deciphering the meaning behind the greetings, meeting colorful characters, and piecing together a conspiracy that links a rogue AI to the invasion of these oddly cultured hellos. As you progress, your choices shape how the society reacts, either embracing the change or spiraling into confusion. With each unique interaction, you unlock new areas, and secrets, and perhaps even discover your own hidden talents for language and persuasion.
