I actually love Draco and Bella's character. I find them so intriguing. Especially Bella. I want to know her story.. we really don't know much about her. One of the only parts I liked about the epilogue is that Draco appears, but JKR really leaves it up to the reader to decide weather he is good or bad in the end. There has always been a back and forth debate over Draco. Is he evil because of pressure, does he really want to be a death eater? ect. But, I love both of their characters. They add a lot of depth to the story.
