The Guardian of the Evil Lover

In an accident, she rescued an injured fox. She only kept it as a pet. Unexpectedly, she woke up one day and found that the fox sleeping next to her had turned into a charming man. OH MY GOD! Her weak heart could not withstand such stimulation. The dream must be a dream, a terrible nightmare. Unfortunately, this is not a nightmare, "From now on, you can only have me in your eyes, and you can only have me in your heart." She wanted to cry without tears, how could her docile and well-behaved fox become like this, "No~" She looked up to the sky and screamed. He rescued us in time when we were in danger again and again. Is meeting him a blessing or a curse? He whispered in her ear, "I will protect you until the end of my life." She melted his heart that had been frozen for thousands of years. He protected her life, and she protected his heart. Who protected whom, or each other, until the end of life and until the next reincarnation...
