I don't think there was? I like wives-fic, and OT3/OT4, so when I saw the prompt for RBB I thought I'd like to try my hand at it! And then I just listened to all the songs and got my ideas from there, it was really guided by the lyrics & atmosphere of the mix. I didn't really have an OT3 bunny that I always wanted to write or anything.

Generally the way stories start for me is with a line more than a scene - which is also why I get stuck so often! lol
