Answer:
Lin Manuel Miranda retold the story of Eliza and Hamiltons meeting from different perspectives because the author wanted to give more perspective and ideas to the reader. When you read the story from another perspective it helps you understand the story better.
Most stories are told from a single perspective—whether that’s an omniscient point of view or a close third-person point of view that is tuned into your protagonist’s thoughts. But sometimes your story feels so expansive that it’s necessary to tell it from more than one character’s point of view.
