In this AU set during the rebuilt Hogwarts of 1998–1999 (post-war, with older students returning and younger ones continuing), Cass (7th year Gryffindor Chaser, 18) and Astoria (6th year Slytherin, ~16) are openly dating. The war’s end has shifted attitudes: house rivalries linger but aren’t absolute, pure-blood prejudices are fracturing, and their relationship becomes a quiet symbol of change—bold, visible, and unapologetic.
