Dosed with love potion (Rewrite)

Harry was far from an ordinary boy, particularly by the standards of the Wizarding World, and her husband was gradually revealing his true nature. Aunt Petunia was acutely aware that baby Harry did not exhibit the typical behaviors of an infant—he neither cried, laughed, nor screamed like Dudley. She discerned the signs, having secretly perused her sister's books in her youth, captivated by potion-making.Petunia recognized that Vernon was no longer the man she had wed. The kindness that once characterized their relationship had dissipated, replaced by a harshness that left her increasingly isolated. He frequently reminded her that a good wife "keeps her damn mouth shut!" This oppressive atmosphere became intolerable, and she could no longer endure the abuse.In a desperate bid for freedom, Petunia resolved to escape her husband's tyranny. She gathered her four-year-old nephew, Harry, along with Dudley, and set out to seek the one person she had never imagined approaching for assistance. Deeply concerned that her sister had been subjected to a love potion during her pregnancy, she sought out Severus Snape, hoping he could provide the aid she desperately required.
