Kim Doyoon's absolute secret is that he's a half-vampire. Lately he hasn't been able to consume any human essence so he's on a poor state making him feel very tired at work. While dozing off he accidentally messages the chief/director of his company, Lee Kangwoo, "I've been thinking about it and I guess I'll need to get a sex partner". It was too late when he realized his mistake since Kangwoo had already told him to come to his office later. But Doyoon is surprised to hear that Kangwoo is willing to take his offer of being sex partners! What are the reasons of Kangwoo to accept such proposition? Are there feelings involved? Does Doyoon feel the same? Will Doyoon be able to finally feed on essence?
