Toyama Saki, editor of Harukawa Literary, has been transferred to a literary magazine that she has longed for, and is eager to acquire the rights to publish a new work by up-and-coming female writer Azuma Yoko. Meanwhile, Yoko, who is in a slump, suggests that she actually tie up women. Saki signs a contract to spare no help in exchange for Yoko's publication rights, and in hoping for Yoko to write, she becomes a model for bondage training and falls into the world of SM.
