Austin's song AU

[apipsc.livejournal.com]

 Ok, so I searched this tag and didn't find it. What I remember about this story : Brian changes his message on the answering machine  and most of the time I remember it ends with 'PS: and if this is Justin I still love you' . And I know this is a song-fic based on Austin by Blake Shelton .
I just can't remember where I read it or who's the author !!
If you know, I really apprecciate your help.

FOUND ! [by the author] It's The Message by faramirhaldir . Thank you.
