Do you have any romance novels that you recommend?

The male protagonist married a volunteer at her mother's hospital because of her mother's last words before she died (I seem to remember it). However, the male protagonist did not like the female protagonist at first. Every time they had sex, the female protagonist had to take birth control pills. In fact, the female protagonist loved him. Later, because the female protagonist misunderstood that the male protagonist had an affair with another woman, they divorced. After the divorce, the male protagonist found out that he also fell in love with the female protagonist. I still remember some scenes in the movie. After the male protagonist took a shower, The female lead would always prepare juice for him…She also remembered that one of their servants had told the male lead's wife that she would change the curtains every season after their divorce…Also, after they divorced, the male lead found the female lead and was very happy to see that her dormitory had a single bed. She even threw away the flowers that other men had given her…I especially remember that when they were having sex again, the female lead said that she hadn't taken her medicine yet, and the male lead said that it was a good time to have a child. He only remembered so much…I've been looking for this book for a long time, but I can't find it. Can anyone tell me if they know? thanks
