It seems like you might be referring to a narrative technique or a storytelling element where the perspective shifts from a retrospective view (looking back at the past) to a more forward-looking or present-focused view (moving towards the future). This type of change can significantly impact the tone and direction of a story.
In literature, a shift in point of view can enhance the reader's understanding of character motivations, emotional growth, or the consequences of past actions. It can also create a contrast that highlights character development or thematic elements related to time, memory, and change.
