Three years ago, the world came to know of the existence of humanoid beast creatures after the government decided to stop hiding their existence from the world. It was decided that they would be integrated into human society, and thus the "Cultural Exchange Between Species Bill" was created. Since then, the cultural exchange program became a huge success helping many species integrate into human society.Kurusu Kimihito is a volunteer (?) in this exchange program who has been given a Lamia (Snake Girl) named Miia to take care of. After spending some time together, Miia has fallen in love with Kurusu, which isn't a bad thing per-say. However, there is a stipulation in the exchange program that prohibits interbreeding between humans and beast creatures. Violating this law results in a severe punishment for the human. Will Kurusu be able to resist Miia's advances and keep himself out of trouble?
