Kaya Satozuka is a brilliant secretary who excels at her job, which is why she doesn't bat an eye when she's assigned to be personal secretary to Kyohei Touma, the very difficult managing director of Touma Foods. It doesn't faze her when her new boss seems determined to make her fail, and she even manages to take it in stride when she discovers the secret behind his prickly behavior…he's a vampire! But while Kaya easily adapts to late nights and keeping a schedule of his "dinner dates", will her ultra-competence help when Kyohei's smoldering gaze starts turning her way?!
