I Can See Malice: Reincarnated as a Human Just to Protect Her

I was a Siamese cat. He is born with the ability to see the evil in the human heart and smell the rot in the soul. So, all the men who are close to her—— They were all driven away by me. Because they don't deserve it. She is my only master. Gentle and kind, but abandoned by his marriage, dragged down by illness, and struggling alone in this world. Until the day I died, she held me and cried until I collapsed. Only then did I understand—— She had no reason to continue living. Cat God gave me a choice: Become a demon or an immortal. But I only ask one question—— Can you please make me a human being? In this life, I went back to her poorest and most helpless childhood in advance. Since I can see the evil in people's hearts—— So in this life, I blocked all evil for her and protected her for the rest of her life.
