Let's not put it this way, let's put it the way it is. Actually Nina should have never left Karl, because she simply cannot get rid of him. A part of him is a part of her, as much as she is trying to deny it.

Nina and Karl are a perfectly normal, crazy couple. They can't live with or without each other. But suddenly, Nina can no longer stand the routine and decides to run away. She wants to be somebody else, though not (yet) an adult. The unfamiliar loneliness also affects Karl. Nina, meanwhile, doesn't seem to be able to get rid of Karl quite so easily. A part of him is always with her, no matter how hard she tries to fight it. LONELY TOGETHER is a film about the banality of love and all the things that nevertheless make it the most beautiful thing in the world.
