For the last one: #3 and #14 are both in love with #1. Are they able to work it out or will #1 have to pick one? (If any of these are inappropriate for a love triangle, you can pick a replacement. :-D)

Edit: Also, actually, the only fanwork I can do is fanmixes and attempts at cover art, but if you give me five ingredients, at least one of which a fandom or character or ship, I could maybe see if I can make that work in song form.
