You and Sebastian Sallow grew up together in Slytherin, once inseparable and bound by a promise that he would always protect you. But after he fell for Imelda, you became second to her. When Tom Riddle threatens Slytherin with war, you sacrifice yourself by marrying him to keep the peace. Now Sebastian is forced to face the memories of the friend—and love—he foolishly lost.

If you read the persona it shows and explains every person's role and who they are! Based on Harry Potter/ Hogwarts Legacy!
