B/J fic centred on Justin's birthday

[quirkyeyebrows]

Hi all -

Looking for something I thought I'd bookmarked. It shows Justin's birthday over several years and the different ways Brian behaves. I think one year Justin blackmailed him into being the perfect boyfriend all day, then another Brian ignored him so he went to a lesbian bar??

I remember it being great. Love to find this specific fic but others with similar structures are also welcome. Thanks in advance!
