Harry Potter: Wait, How Did I Become a Heartthrob?

[Mary Sue + all-pairings + beloved by everyone + omniscient perspective = a happy ending for all] Li Qingxue, who died suddenly after staying up too late, caught the transmigration wave and was reborn in the world of Cardcaptor Sakura as the eldest daughter of the Li family, the child of the Sakura and Syaoran pairing she shipped with all her heart! The year she turned eleven, Dumbledore suddenly showed up at her house, making her already fantastical life even more unbelievable. An acceptance letter? Going to study at Hogwarts? Awesome! She'd been eager to show off her skills, with Clow Cards in one hand and Chinese Taoist magic in the other, ready to punch Voldemort and kick Death Eaters, save everyone from their regrets, and, while she was at it, give the handsome young Savior a little extra love. But the plot and everyone's behavior gradually started feeling more and more off. With a crowd of guys surrounding her, she rubbed her aching head: Stop it, you guys, don't fight anymore! I'll be heartbroken if even one handsome guy gets hurt! Oh my goodness, I only wanted to be a savior. How did I become everyone's sweetheart?!
