Sure, he's rude, dismissive, keeps odd hours, and keeps bringing women into the office late at night for sex, but Kaya works hard to overcome her distaste for her boss and perform at her best. Then she discovers that Kyohei's late night trysts are in fact late night feedings. Her boss is a vampire, and only Kaya and Kyohei's brother know the truth. Now Kaya must not only keep her office running smoothly but also keep her boss's secret. What will happen though when warmer feelings start to interfere with her duties?
