Snow Moss is Sirius Blacks new best friend. Tired of casual flings with the pompous prats of high society London but has no luck in finding someone worthy of being her boyfriend. That is, until Sirius' brother returns from where he was out of the country on business. After a one night stand on the night of James and Lily's wedding, feelings spiral out of Snow's control.
"Okay, you want my advice? Keep it casual with Reg. You two are sleeping together, keep it that way. Don't tell him how you feel. Swallow these feelings until they eventually wither and die. Or, don't. I don't really care. Tell him, if you want. But he's not gonna go 'Oh, Snow! Let's...run off into the sunset together and live in a little cottage and only have sex with each other!-' "
"Alright!" Snow cuts him off with the shove of his shoulder. "Thank you, Sirius, really. Big fucking help."
Sirius grins, amused beyond belief. "Welcome, Snowy."
very LOOSELY based on normal people + various himym references
