I recommend two modern romance novels," Eroding Feelings: Mr. He, Don't Be Messy " and " Obediently Submit to Satan's Attack ", because they were both related to Satan and matched the plot of the Blue Exorcist Doujinshi, Satan's Daughter. " Eroding Feelings: Mr. He, Don't Do Anything," told the story of the love and hate between the female protagonist and Satan, while " Satan's Attack: Obediently Submit " described the story between the female protagonist and Satan in the form of a romantic youth campus. I hope you like my recommendation.
