Sansa x Margaery Harry Potter AU - Sansa Stark is the brightest witch of her age, but spends her life engrossed in books, an unusual trait in a Gryffindor. Studying late one night in the library, Sansa meets the dark and tempting Margaery Tyrell, a Ravenclaw student two years above her. The older girl is flirtatious: offering a wink as she turns down a corridor, a lingering caress of Sansa’s shoulders as she passes through the Great Hall to sit with her friends, or a longing smile from across the library. Instantly, shy and withdrawn Sansa becomes enamoured of her. Margaery remains fairly aloof… Until Sansa has had enough and confronts her in the Great Hall after dinner, drawing the attention of every Hogwarts student and professor.
