I Apparently Tumbled Into Another World Like an Onigiri, Where I Meet the Demon Lord and a Rotten Literature Girl

I was struck by an impact on my way to school, and when I came to, I was lying on the floor of the Demon King's castle. The Demon King thrust a book from the human world at me and declared: "It seems in the human world, it's okay to fall in love with a man who has fallen from the sky!" Who did it! Who gave the Demon King such strange knowledge! This is a short short story for a radio award.
