Set in a vibrant and chaotic festival of greetings, players assume the role of a friendly but forgetful local who discovers that everyone in their town is suddenly plagued by a bizarre phenomenon: they can only say 'hello' to strangers, with no memory of their previous conversations. As the festival unfolds, you must navigate a series of quirky relationships, overhear secret exchanges during high-energy greeting competitions, and decipher cryptic messages hidden in the banners and decorations around the event. The goal is to uncover the source of this greeting epidemic, all while trying to maintain friendships and unravel a whodunit-style plot filled pure hilarity, chaotic interactions, and dramatic revelations.
