Hey guys, fic searching again.
I can only remember snippets of the fic which is making quite hard to track down, but I'm pretty sure it was along the lines of Brian pushing Justin off the Kinney Cliff.
The bit that's clearest in my mind is after a confrontation at the Diner, Justin returns to the loft and is standing in front of the large window with his arms outstretched as if wanting to fly away/fall. Brian walks in, sees him at the window and asks if he really makes him feel like that (as though he wants to fall), Justin replies that he does sometimes.
I think the scenes/chapters of the fic corresponded with either the seasons or a series of paintings/colours, but I could be mixing that up with another fic.
If anyone has any idea of what the fic is or where I could find it I would really appreciate it.
Thanks
