In the setting sun, it strikes me with the contrary between Naoji and Kazuko’s choice towards love and life, as well as their moralities. Naoji who is always struggling in his life finally commits suicide. He wants to be “as the same as other people” although he feels somehow reluctant to it. He tries to pull him out of the aristocrat but finally fails to do so. In the last sentence in his testament, he says, “I am, after all, an aristocrat.” This struggling deepens in him and finally collapses. Moreover, his hopeless love brings him into another disaster. He can only force himself approaching her husband in order to grasp a glance on her. He can’t love other women nor can he get the one he loves. He keeps it a secret and is being left with the sorrow. In the end, he pursues his own liberty, the liberty of life and death. On the contrary, Kazuko steps out to her love bravely. Without even thinking of giving up, she keeps writing him letters, expressing her love towards him directly. Not getting any replies back, she finally sets herself out to see him. Also she seems not to be puzzled by being an aristocrat. She can draw herself into field working as a farmer. She can live a life like a country woman in the countryside. In the end, she acquires her object of life by having a baby. She reaches the revolution of her life so that she can carry on her life by her own and raise the child. She is a brave woman and straight forward as well.
