Y/n started half way through the year and immediately caught Sebastian’s eye. Her brilliant green eyes and soft black hair make her look like a doll but after beating him in a dual, he knows she is the most powerful of all. When a troll breaks into Hogwarts and nearly tramples her and him, he sees just what ancient magic she can wield and wonders if it’s enough to help save his sister from her curse. His crush for her only growing as they go on an adventure together. Him taking her for all his bad boy adventures.
