Jessica's mundane existence unravels when she learns her seemingly ordinary parents—a dentist and a teacher—are secret vampire hunters who expect her to carry on the family legacy. Determined to debunk what she believes is an elaborate delusion, she enrolls at a university where an alleged vampire supposedly operates, hoping to prove once and for all that such creatures are pure fiction. There she finds herself caught between an eclectic circle of misfits, including devoted anime enthusiasts, and the persistent social pressure of the school's popular crowd. As her investigation deepens, she develops an unexpected attraction to a cryptic student who fits every vampire stereotype imaginable—unnaturally pale, strikingly handsome, nocturnal, and perpetually shadowed in dark cosmetics—forcing her to confront the possibility that her parents' world might be far more real than she ever wanted to admit.
