Please recommend a novel that traveled through ancient times.

I read an ancient time-travel novel a long time ago. I forgot its name. Does anyone know it? The female protagonist was a military doctor in her previous life. Later, she transmigrated into the daughter of an ancient courtier's family. She seemed to be a good-for-nothing. The male protagonist was a prince. It seemed that because the female protagonist saved the male protagonist, the male protagonist relied on the female protagonist. Because the male protagonist could sleep well with the female protagonist in his arms, he would flip through the window of the female protagonist's room every night. Then, the female protagonist fell in love with the male protagonist, but the male protagonist seemed to only have a good impression of the female protagonist. In any case, he was super torturous. He tormented the female lead and loved her but could not get her.
