I am a witch, wandering the city alone!Once I tried to keep the warmth around me, but found my fate irreversible

A thousand years of loneliness, a vampire's heart can't beat, and legend has it that only the original vampire has ever had a heartbeat, and no vampire has ever had a heartbeat, not even the one he saw when he saw Serena, and that's when Kris felt his first heartbeat, and from that moment on, his loneliness took on a new color, a preference that was only for her.
