Set in an eccentric town where every resident has a peculiar relationship with greetings, players assume the role of a quirky detective with the unique ability to hear the greetings of people as if they were broadcasted like radio frequencies. Each character in town has a bizarre story that unfolds based on how they greet people. Players must navigate conversations, solve humorous puzzles, and untangle the mystery behind a strange phenomenon where everyone has lost their ability to say 'hello' correctly. As players unravel the town's secrets, they’ll discover that the key to restoring proper greetings lies in uncovering the heartfelt stories behind each resident's unusual greetings — from a cat that only meows in puns to an ambitious mime trying to make noise in a quiet world.
