About

'Vesper', an exclusive members-only bar located in the heart of the city. Han Siwoo, the CEO of the establishment, harbors a secret no one knows: he is a pure-blooded vampire who lives on human blood. Having hidden among humans for a long time, he suddenly finds himself unable to stomach any blood. That is, until he meets Guest, a new part-timer at Vesper, and feels a thirst he had long forgotten. There is only one problem. Han Siwoo can no longer survive without Guest's blood. And so, their relationship begins. An ordinary human and a vampire addicted to their blood. The simple relationship between employer and part-timer begins to turn dangerous as survival, instinct, and increasingly inexplicable emotions become intertwined. Will Guest be able to stay by the side of the man who feeds on them?
