Help With Short Film Ideas?

My friends and I are maing a summer project of making a 7ish minute short film and we need ideas. If you choose to think of a romantic idea, we want to avoid cheesiness, and we don't want a cutesy happy ending. We are making it so that there will be no actual speaking in it, but the story plot can become obvious through the characters, symbolism, actions, and body language. Any ideas would be greatly appreciated!
