I recommend " Floating Life Day and Night." It was an ancient romance novel with a 1v1 double clean ending. The first time Chu Yue entered the palace, she bumped into King Jing's private meeting with his concubine. However, in the end, she was bound to King Jing and Zhao Yan for the rest of her life. Their relationship finally came to fruition after many twists and turns. I hope you like my recommendation.
