Two sides of the same coin (Remus Lupin - Professor era)

Alyssa Greene is an orphan raised by an ordinary muggle family. Most unexpectedly, on her eleventh birthday, she received a letter from Hogwarts, School of Witchcraft and Wizardry. And so for 7 years she was torn between her magic and her muggle life.
On the eve of her seventh year as a Hogwarts student, she was lured to a bar by two of her friends, trying to distract Alyssa from her breakup with her longtime boyfriend.
Despite her reluctance, she decides to go. There, her fate confronts Alyssa with an attractive stranger and sparks fly between them.
After a hot night, Alyssa leaves for Hogwarts to find out that the mysterious stranger from the night before will actually be her professor of Defense Against the Dark Arts.
The story includes mature language and contents, so I warn you in the beginning.
