Professor Malfoy?

She was old enough to know better. He was young enough to forget the rules. When their secret is exposed, love becomes a crime - and running becomes their only choice.

When Alisha returns to school for her sixth year, she expects familiar halls, old friendships, and another ordinary year at Hogwarts. What she does not expect is him: a young substitute professor with a cold stare, a guarded past, and a presence that unsettles her from the moment he enters the room. Professor Malfoy.
At first, their connection is quiet and dangerous - lingering glances, conversations that last too long, and feelings neither of them should admit. With only a few years between them, it becomes easier to forget the rules separating them. But secrets rarely stay buried. When their relationship is exposed, scandal tears through the school. He is dismissed, threatened with prison, and branded as a disgrace, while Alisha is forced to face the consequences of loving someone forbidden.
Refusing to let others decide their future, they do something unexpected.
