Thank you for this insightful comment that touches on the key themes of the story.
If I suddenly became aware of my past lives, who would I become? What would become of my existence?
This is a great dilemma. On the one hand, a reincarnated person will have knowledge and understanding that could enrich experience. But it also opens other potential issues like loneliness and regret. It's a vexing mystery. In the story, the pair remember working on some big project, so it gives them a sense of purpose.
Thank you for reading.
