The movie is about life and death, unconditional give-and-take between strangers. Sympathy is the beginning of a dying person's rebirth. Two characters were facing their extreme pain. Still they eventually overcame these hardships, no matter which ways they chose or God let them. In the end, I almost cried and thought they should have been together. But then I thought again and felt I was fine with this ending. Nothing is perfect. It is life. When we understand its imperfection, we understand that it is the journey (many times not the result) that brings hope and lessons when we need it the most.
