Can you recommend a novel that makes me feel sad?

, I recommend "Book Traversing the Interstellar Era" to you. This is a sci-fi space-interstellar love song novel. In the story, the main character was dressed as an invisible person that even the male and female protagonists had never seen before. Although she could reverse the fate of the original owner, the apocalypse of the entire star field was about to arrive, so this was a very sad story. I hope you like this fairy's recommendation.
