As the Ex of Bat and His Son, Who Am I?

[A product of the novice era, very Riddler, please be careful before entering! It was originally a story about fast travel, but I tried to change it into a story about the end of the world to fill in the gaps. You traveled through time, you traveled to Gotham in 1998, became Falcone's daughter and Bruce Wayne's girlfriend, and learned about your death date from certain aspects that cannot be told to others. You struggled, but ultimately died in front of the new Batman. Fifteen years later, you were resurrected and had the honor of becoming his son Dick's girlfriend. Things to note: Riddler. The plot is very convoluted. The male protagonist, I guess, is Bruce Wayne. Because it has been overhauled, the comments in the comment section are completely inconsistent with the text. It is a 21-year-old novel, so even if it has been revised, there are still weird places, and the update time is very irregular. Because it is planned to be completed at 100,000 words, it may be ended hastily. In short, don't expect it! Intention: People's destiny can be changed.
