Prom remembered after dripping paint?

[kato-sama.livejournal.com]

There was that fic, someone asked for it here, I wanted to read it, but never came around to it and now I can't find it anymore. I searched here for hours, last months and tags and all, and I found nothing, so I give up.. help please, people!
Anyway, I just remember that Justin stands in his studio working and when blue paint drips on the floor, he remembers the dance at the prom or something along these lines.. I think it was post-513, but I'm not sure about it, and I can't tell more about it, just these paint dripping on the floor thing, not much, hope someone knows this nevertheless, like I said, I never read the story, but I want to.. help? Thanks in advance!

Edit: FOUND! Links in the comments. Thanks, again!
