This episode is an adaptation of the previously 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.
- This couple only has one appearance together in the entire show. Their storyline continues in a single stand-alone episode in the Junjou Romantica anime that acts as a sequel to this episode.
