Honey blood

When Hinata Sorazono meets her new neighbor, Junya Tokinaga, the author of an incredibly popular vampire romance novel series, she's inexplicably drawn to him. Dressed in a kimono with an old-world air about him, Junya has a taste of Hinata's blood and tells her it's sweet ... In Junya's novels, a kiss with a vampire means that only the human's blood can be taken as nourishment. If that person dies, so will the vampire. Could it be that Junya is actually a vampire and about to enter a life-changing contract with Hinata?
