Title was two names, a short film about two lovers

I saw this short film about 8 years ago, but I’m not sure when it was released. I believe it was older. I think it is foreign, maybe the names were French?

It was a story about two lovers, I don’t think there was any dialogue. The story started out sweet and happy but slowly got darker and more depressing. The girl got injured I think, maybe a broken leg and it was just a progression of their relationship.

Got something to say?
