I recommend " A Concubine in Power: The Cold Emperor Loves to Act Coquettishly." This is a novel about transmigration. After the female protagonist was reborn, she became the emperor's concubine. Because of her agreement and disregard, she attracted the emperor's attention. Later, the emperor's love also poured in. In the end, the female protagonist became the empress and was with the emperor one-on-one. Before the emperor met the female protagonist, he had no one he liked. I hope you like my recommendation.😗
