B/J fairy tale sort of

[minami77.livejournal.com]

Hi, this is my first post here!
I'm looking for a fic I read some time ago but I can't remember title or author.
Here what I remember: Gus is reading to Brian a tale he wrote with Justin's help. The story is sort of a metaphor of Brian and Justin relationship. there is a man who give to a guy a lot of colored air balloons but the guy is not happy so he go away again and again with other men until he understand who is the real man who can make him happy and make his world full of colors.
I think Justin was in NY and in the end he is at the loft door. I checked the memories but I didn't find it.
Sorry, my English is not very good, I hope someone can help me.
Thank you.

EDIT: Found it! it was The balloon man  Thanks to phnzz
