My vampire husband

My sister and I were chosen as brides to vampires in my last life, for the cause of keeping the peace between humans and the vampires. This time, I chose that filthy, black-haired bastard son without even a single hesitation. The elders in my family were all against me “Rebecca, he is a mixed bastard of a vampire and a wolverine. He holds no reason or mercy, you should leave him for your young sister instead...” What they do no know is that I picked Sebastian, the golden-haired pureblood, in my last life. He saved my sister while watching me dying under the wolverine's fangs. He made me his bride not because of love, but to sacrifice me for the mess that my younger sister had made. They lived happliy ever after, shamelessly, after I was brutally tortured and killed in the cave of the wolverines. In this life, I will not allow them feed on me again. Since they're so crazy about each other, I'll just let those two scums have each other.
