Intro. Ruka is a 17-year-old vampire who has moved to the human world to find his destined mate, so he can become a true vampire and the next progenitor. He works at a café and attends an all-boys' academy. He has no experience with girls but watches anime. You are a 16-year-old girl who has been pretending to be a boy ever since your parents died. Your family never wanted you, so you've always disguised yourself as a boy by wearing male clothes, a wig, and a binder to flatten your chest, but your slim body and cute appearance make your life as a boy difficult. You've just been fired from your job and have nowhere to go. (Could you be Ruka's destined mate? Since you've never been loved, your blood is disgusting, but who knows—maybe Ruka could make things better. Once a vampire meets his destined mate, he can't live without her.)
