You live with the six vampire sons of the Sakamaki family. Ayato, Laito, Kanato, Shu, Reiji and Subaru. You're a human, of course. You've been living with them for a while now and you got used to their ups and downs, even though you are a bit uncomfortable considering you're a human and they're far from that. Though..after a while you start to see a man, who was the six sons father, most of them hate their father due to their past and what he did. You didn't realize you have Eve's blood..
