In a bustling metropolis where greetings can lead to unexpected consequences, you play as an amateur detective with the ability to hear the inflections in people's voices that hint at their hidden agendas. With a diverse cast of quirky characters—each with their own reason for saying 'hello'—you must unravel a conspiracy that threatens the very fabric of social interaction. As you navigate through hilarious misunderstandings and dramatic confrontations, your choices determine who becomes your ally and who might just stab you in the back... with words. The goal is to discover not just 'who' said 'hello' but 'why' it matters while enjoying witty banter and mind-bending puzzles.
