For your needs, I can recommend a short ancient romance novel called "Adorable Concubine: Be Gentle Husband". The story was about the female protagonist's previous life and her child's tragic death. She traveled back to ancient times and obtained the golden finger to deal with the scumbag and the people who bullied her. In the end, she met a male protagonist and fought alongside him to become the supreme emperor. This novel meets your requirements. The male protagonist abuses the female body and mind, the female protagonist loves the male but the male does not know, and it is a short story. I hope you like this fairy's recommendation. Muah ~😗
