C'mon people, recruit more people to the community!
This round's theme is very broad - Unrequited Love. People who should have been together but weren't, this can include slash pairings.
To give you some ideas. . .
Buffy the Vampire Slayer - Buffy/Xander, Xander/Willow, Anya/Willow (at least I think so)
Lord of the Rings - Frodo/Sam, Aragorn/Eowyn, and so on. . .
I'm only giving you one more week. That's because I want to fit in another contest before I go off to Italy for five weeks in May.
