Some people promise to change even when things look like they will turn out bad. Draco Malfoy promised himself during the Wizarding War that if everything turned out well, he would change. He would no longer be a Death Eater, he would try to get the girl that he loved but couldnt be with, and he would make people believe that change happens. Some people promise to believe in change and will do anything to help those who want to change. Hermione Granger promised to believe in change when she was a young girl. She still keeps that promise even after the Wizarding War. She would always give people a new chance to start over, she would believe in those who want to change, and she would help people that needed help to change. It is quite amazing that both of them have made these promises. To Hermione, it will be the happiness and content in helping someone. To Draco, its always her that makes him happy and content. Soon she will learn that he is for her as well.
