Sirena Miller has spent five years on the edges of the Great Hall, watching the Marauders. The four boys who move through Hogwarts like they own it. She's never worked out how Remus Lupin fits among them. Quiet. Careful. Then a detention gone wrong sends her into the Forbidden Forest on the worst possible night. She wasn't supposed to see what she saw. What starts as curiosity turns into something far more dangerous for her heart. Remus Lupin x Fem OC [Marauders Era] [Slow Burn] [Pining] [Light Angst]
