The life of a boring salaryman-turned-vampire gets turned upside down by a handsome coworker who's just dying for a bite!

A scrupulous vampire happy with his mundane life finds himself perpetually tested by his bored—and very unscrupulous—coworker.

Office worker and 40-year-old virgin Minoru Sayo lives a simple, perhaps boring, life—at least until the day he is turned into a vampire! Unable to bring himself to drink human blood, he satiates his overwhelming thirst with cats. But one night, after a disastrous mixer, Minoru is pushed to his limits when a junior colleague passes out drunk, neck exposed, while waiting for the train. Unable to resist, Minoru sneaks a taste. But all is not what it seems with his hapless coworker, and Minoru’s life is about to take yet another unexpected turn!
