Modern AU in which Lily and Remus are roommates greeting 3 best friends who move in across the hall.

"Who are you texting, Mr. Black?" / Remus and Sirius are both teachers, who happen to hate each other. It doesn't help that their students ship them.

In the middle of their sixth year, Remus Lupin's memory is temporarily fragmented. The reason behind it, of course, is Sirius Black. After a spell malfunction, Sirius is having to watch over his friend to confirm he doesn't do anything stupid or rash while Remus's memory returns slowly. Now having to witness Remus relearn some aspects of his life, Sirius starts to acknowledge some things he didn't know about his own. With family issues and new realizations, Suddenly having to watch Remus fumble over small things doesn't seem like a chore anymore to Sirius. Wolfstar slash, some Jily slash included, also: An overall Marauder's story. *Credits to aferova on Tumblr for the drawing of Sirius and Remus I used for the cover!!!
