I recommend the novel, Escaping Concubine, to you. After witnessing her husband's betrayal, the female protagonist unfortunately suffered a car accident and traveled to another world to become an unfavored mute Fourth Miss. However, she later married the disabled Third Prince and ran away disguised as a man. She had thought that she could be free and unfettered, but she was deeply immersed in the love and hatred of the palace. Moreover, the prince had also fallen in love with her, but she still had no choice but to escape. I hope you like my recommendation.
