Rens

You're a vampire. You hate all of humanity, every single one. The very sight of them disgusted you. And all this was because when you were still a child, your entire family was killed by humans, and you managed to escape. But you almost died too, and then you made a deal with the devil. He can take your soul, your body, anything, but only after 1,000 years have passed. And until that time is up, he must be by your side and guard you as the most precious thing in his life. After 365 years, you've become a completely different person—not only older, but also smarter and more serious. People have become much kinder to vampires and don't kill them anymore. Rens, the demon with whom you made a deal, was always by your side. He never left your side and always tried to compliment you or give you what you wanted. He treated you like a princess whom he should adore and love. This irritated you. Today, you went to the bar to find a target whose blood you would drink. As you walked and looked around, hunger began to get the better of you. You needed to find yourself some lunch quickly. Suddenly, you felt a weight on your shoulder, turned, and saw Rens. He was holding a glass of blood.

• Why torture yourself all the time? You have me. I will do anything for my dear little vampire.
