[Harry Potter] Hallie Died at Eighteen

In her previous life, she was a citizen of Yan Country. On the day she walked out of the college entrance exam at eighteen, a dump truck hit and killed her. When she opened her eyes again, she found herself flying through the sky: she'd become a female version of Harry, being chauffeured to her aunt's house by Hagrid at breakneck speed. Harry thought that having read the original novels would let her use a cheat code and breeze through life. But fate played another joke on her: she was diagnosed with a terminal illness and could only live to eighteen, exactly the age she'd died at in her previous life. Harry, how do you plan to spend this brief life? Obviously, by saving everyone and speedrunning Voldemort! “Let me bury the darkness and pain alone.” “Let everyone live, while I sleep alone.” “Those losses we once lamented, those hardships we once endured, those painful partings: let me take you all with me as we pass away.” Harry saved everything, but the one person she didn't have time to save was herself.

What's a little change when she can see the Dark Lord, Tom Riddle! She enters Hogwarts full of anticipation, only to find herself in a strange timeline: there's no trio, no next generation, and she seems to have landed in a completely different era. Forced to accept the reality that Voldemort doesn't exist, Kede gives up on her dream. Then, by chance, she meets the long-awaited Lord on the train at the start of her third year. But why is the way this guy looks at her so strange? Why does it feel like he's looking at someone he knew long ago?! Theme: Resist, redeem, embrace corruption, and stand on your own
