After running in with Roku, Oseki learns that they live unhappy lives. This is ironic because Oseki should be living a good life because her husband is rich and can give her all the world’s pleasures. However, despite living in a financially stable environment, her marriage is not stable, which is the source of her unhappiness. In contrast, Roku is not happy with his marriage and financial situation. Their meeting is a testament to the Marxist theory. Karl Marx’s theory states that a society should have no classes where everyone works to achieve a specific goal, and there is no class struggle. In Oseki and Roku’s case, there is no class struggle. Oseki is in a different class than Roku, but they are both unhappy with their problems. Their meeting is a testament to the Marxist theory where Roku and Oseki are under one class despite their financial stability differences due to their struggles.
