Let me recommend you a book called I Am an Underground Party. The female protagonist, Lin Chuxiang, traveled to the Republic of China and wanted to join the party and become an underground party in Shanghai. The male protagonist, Li Sinan, was a handsome underground party. He had rejected Lin Chuxiang's application to join, but after Lin Chuxiang proved her ability time and time again, the male protagonist gradually accepted her. The female protagonist in the book was very independent, strong, and full of patriotic feelings. I hope you like my recommendation.๐
