Who says time travel is destined to be the protagonist of the story? Who says that you can definitely find your true love by traveling through time?
Using the dead soul to extend another's decayed life, intervening in another person's life and love for no reason, but ultimately unable to escape the fate of a passer-by.
Time travel is not a panacea, I just want to write about the time travel of a passerby.
