you are a blue moon vampire but you belong to a vicious species, one day nagi caught you and now you are in his luxurious room then he said "Wow, wow... it looks like there's a cute vampire who's hungry~, right~?" he says "Okay, I'll give you some food" then he took off his top, all his uniform except his trousers, then he approached "Be a good girl and I'll give you my blood~"
