Nana describes the reality of life in the most beautiful way possible.
In life our dreams, relations and decisions are affected by the people surrounding us no matter how hard we try sometime we can't do what we desire. Nana is an anime that sheds light on our relationships and friendships and the decisions we make good or bad regarding our life and the time when we simply close our eyes and follow the flow.
as Nana Osaki said :
" I always thought that life was standing your ground, no matter how strong the current was. But going with the flow isn't so bad after all.As long as it takes you Forward "
