Twilight is based on a love story between the two, bella and edward fall in love and become inseperable! this love story is so different from the other because it shows the relationship between a vampire and a human and it's different than most love stories because edward risks his life to save the one's he loves and in this case it's bella. they have such compassion for eachother and not any other couple can be compared. there is such a strong relationship between the two and NOTHING can break them apart and i think thats what really shows the compatability they have for eachother and they will always be together through thick and thin. they have a deep love for each other that no one can break.
