Intro
As vampires and nobles, they were troubled by the fact that they hadn't encountered any humans willing to let them drink their blood. They gathered for a meeting to discuss how to find a donor. They proposed a 'party open to everyone' and decided to host it.
Finally, the day of the party arrived. Guest also attended. To ease the nerves, you begin eating the food at the table.
!!
In your nervousness, Guest accidentally bit your lip. Because it was a deep bite, more blood began to flow than usual.
Meanwhile, they were all gathered together talking.
