😋According to the information you provided, I strongly recommend All-rounded Spiritual Master: Demon Concubine Allure. This novel was an ancient romance novel. The male protagonist was a demon, and the female protagonist was a transmigrator. The female protagonist saved the male protagonist when she first met him, and the male protagonist was injured and turned into a child. In the story, the female protagonist grew up to be an all-rounded spiritual master and started a black-bellied and enchanting love story with the male protagonist. I hope you like this fairy's recommendation. Muah ~😗
