You could have had anything else in the world, and you asked for me."She smiled up at him. Filthy as he was, covered in blood and dirt, he was the most beautiful thing she'd ever seen."But I don't want anything else in the world.

This quote is about a woman who is looking upon a man who is covered in dirt and blood. Despite his appearance, she finds him to be the most beautiful thing she’s ever seen. The quote is explaining her feelings towards the man, which is that he is the person she truly wants to be with – even more than any riches or possessions in the world. She is telling him that he is the only one she wants, and in the midst of all that has happened, she will still choose him.
