Ten Days Until the End: Traces of Time

[Some Honkai: Star Rail abilities + Ten Days + A New Ending] What is [the passage of years]? What is [time]? [The passage of years] and [time] are much alike, yet different. [The passage of years] can watch over the past, record the present, and write the future. [Time] will bear witness to it all, then forget it. And when the two intertwine, they become [fate]. “What kind of ending could possibly be worthy of all the hardships along the way?” The girl holding a pen often asked herself this. “My story has come this far. What comes next is ‘our story.’ Remember me with [love], like the one unchanging postscript in every poem that has passed away. [I will wait for you in the past.]” Those were the girl's final words. [She will bring the story to a perfect close.] She kept murmuring them. There are no pairings in this book except Zhang Linyue and Chen Junnan! Don't force them together! Chen Junnan's scenes appear around the middle. If that's a dealbreaker, feel free to skip them! It's not really a pairing anyway, just friendship (.’▽’.). The plot follows the original, though some details will change. Please take note! Some characters from Honkai: Star Rail will be mentioned in the story. This is a plot hint that will be explained later! The protagonist, Zhang Linyue, has a split personality, and both personalities know of the other's existence. The story contains selfcest, and the second personality is a little crazy. I've filled in a few details I think the original author meant as foreshadowing, even though the details were never explained. This book also has mysteries and wild ideas, with twist after twist! It may not be as mind-bending as the original, and my writing isn't very good, so please bear with me.
