I recommend the novel " The Beast's Nature Is Hard to Train ". The protagonist, the wolf demon, Quan Rong, was cannon fodder in every life, while the male protagonist, God Forgotten Xi, became a bloodthirsty and violent demon because of his inner demons. It was similar to the feeling of banishing an immortal. Later on, they had a relationship, and Wang Xi became even more evil. I hope you like my recommendation.😗
