The book is called Pride and Prejudice. Darcy, the upper class, suffers from Prejudice, and Elizabeth, the middle/working class, suffers from Pride. It's a lovestory how Love overcomes these two vices in them, even though they clash and gives each other a bad first impression.

You could even argue that they fall in love with each other, because of the 2 vices. Pride loves Darcys prejudice, and prejudice loves Elizabeths pride. So is Elizabeth wrong? Does Darcy not love her, because of her passionate resentment at being looked down upon. But in the Lovestory, they both become the better person as love overcomes the vices, in the sense that 2 wrongs make a right, and that is why we love the story.
