BL Entertainment: Book One What could be frightening enough to freeze the blood of a centuries-old Vampire turned K-pop idol? Being bound to someone. University student Cheong Jin-woo dreams of working in the arts, especially for BL Entertainment and his favorite band, Bam Kiseu. After seeing the band perform, Jin-woo separates from his friends to explore. What he discovers backstage will change his life. Does he embrace it or run? Jung Ki-tae has kept his secret for centuries-until a young fan interrupts his feeding. Even more disturbing is the instant bond Ki-tae feels with Jin-woo-a complication he refuses to allow. Yet resisting becomes increasingly difficult as Jin-woo and a group of students win the chance to make a video for the band, working closely with them for weeks. The obsession Ki-tae felt toward Jin-woo-even before tasting his blood-deepens into genuine feelings, feelings that terrify Ki-tae. But when he finds a way to break the bond, he's torn between severing the connection and protecting Jin-woo.... Especially with a mysterious killer getting closer.
