Searching for K/S kinkmeme post

[sonten.livejournal.com]

Couple months ago I found this prompt - it had multiple (at least 3, and with at least one completed) fills, and for the life of me I can't find it again.
The prompt was something like "Kirk has unrequited love for Spock, but Spock says no - and then a long time later the table turns Spock has unrequited love for Kirk" (this is my short version btw, it was worded differently I'm sure).

So.. help? I'd be happy to read any fic with this theme, but finding that prompt post again would be awesome.
