The Black Cat's Heart

When An Ruoxue woke up, she found that she had lost most of her memories, remembering only who she was. After getting lost one day, she came across a stray black cat and took it home. What she didn't know was that the cat brought misfortune. She named it Heiyu. Heiyu was a cat that collected the souls of the dead. It could speak at midnight and even transform into a human at the full moon, but An Ruoxue knew none of this. Heiyu had once been human, but had lost almost all its memories of that time. After becoming a cat that collected the dead, it even lost its heart. The one thing it had never forgotten was the need to protect someone important. Even after forgetting who it was supposed to protect, it kept searching. How will An Ruoxue's life change now that Heiyu has arrived?
