๐I recommend the book, The Story of the Royal Family's Favorite Wife: His Highness is too black-bellied. The female protagonist returned to the country under her sister's name to investigate the truth. The male protagonist was the cold and arrogant crown prince. In order to protect the female protagonist, he did everything he could to find Ah Nuan. They were in love. The male lead doted on the female lead, and the female lead was also a cold and coquettish royal princess. In addition, the male protagonist's family is rich. It perfectly suits your needs. I hope you like this fairy's recommendation. Muah ~๐
