You know the feeling you get when someone tells you they will love you to "the end of time," the feeling of butterflies the first time you hear it, the warmth in every time that follows? Would that feeling be the same if you knew when the end of time would be? Leah knows, Jeremiah does not. Every day, at the end of every conversation, he tells her, "I will love you until the end of time." Can she go back in time to make it so she can enjoy the feeling of those words again?
