When tragedy struck they stopped being friends. They became hard and cruel. But then tragedy struck his family again and he asked for her help. She agreed and they got closer. Then he stopped needing her help and just needed her and so did she.
It was their last night together. He was going to UCLA she was going to NYU. They spent it together.
The next morning she left. She got on a plane and went to New York.
