Awkward Rondo

"Trick or treat!" The sound of lively children's voices, the usual scene. Just when it seemed like another year would pass without a hitch... "You're so lucky, you get to participate in a game I made!" I heard a voice laughing in the background. Will I be able to escape from this man's game? It was as if I could hear an awkward rondo being played on Halloween. [Translated from Freem]
