HP: the Sickly Eldest Lady Was Countered by the Cure Plan

[Love at first sight + heartthrob + heroine of the Snake Yard + multiple male protagonists + ending if line] After Wen Jinxue died, she was bound to the system 94959, and the system took her to the world of "Harry Potter" that she once loved. She became Daphne's sister through pregnancy, and her systematic mission allowed her to save those things that made readers sad, change the established fate of those characters, and achieve a happy ending. However, things are developing more and more strangely, and the purpose of 94959 is becoming more and more confusing. Does the fate of these people really need her to heal and change? Tentative male leads: Draco Malfoy, Theodore Nott, Blaise Zabini, Harry Potter, Cedric Diggory, Tom Riddle (diary version), Fred Weasley & George Weasley, Regulus Black, Oliver Wood [I don't blame anyone, except the noseless Voldemort. I will try my best to give everyone a good ending. There are many pairs of sub-CPs, and there may be more descriptions, so please don't mind entering them by mistake.
