As for the dance film we watched in the last class,I think it represented the form of love.
At first the men and women meet each other and become one form,then women tends to be dependent on men.Therefore,men wants her to grow up more and be together again in the form superior than before.Afterwards men grows up with the women,too.Finally their relationship gets spoiled,but facing the difficulty of staying together they strive for love they were in before.
