In a bustling, whimsical city that never sleeps, you play as an aspiring detective with a peculiar ability to hear the 'hellos' of people through the walls. Each 'hello' holds a hint about their secrets, fears, and lives. As you navigate through a vibrant tapestry of quirky characters—including a cabaret singer with a hidden past, a reclusive inventor obsessed with talking to cats, and a conspiracy theorist convinced the post office is spying on everyone—you must uncover the bizarre truth behind the mysterious disappearances of certain residents. Each interaction is driven by the choices you make, leading to unexpected alliances, unearthing secrets, and perhaps even solving a crime that’s more than just peculiar; it’s downright surreal.
