This episode is an adaptation of the previously un-animated side story from Junjou Romantica, Junjou Mistake. Originally wanting to be a novelist, Editor Ryuichiro Isaka is torn between choosing editing, which he apparently excels at (he can determine which book will perform well in sales), and writing, which he admits (to himself) that he isn't that good at. He is also struggling with his feelings toward his assistant and longtime companion, Kaoru Asahina.
