The way that Oseki’s marriage is affected by her economic status is through her interactions with her husband. Her husband, Harada Isamu, is verbally abusive and constantly berated and belittles her for her lack of education. For everything that Oseki does, she is ridiculed by her husband who says that so and so is done incorrectly. She cannot socialize well with the other wives of Harada’s colleagues because she has not had the same experiences that they have. Harada would barely speak to her and it made her feel undesired by him. As the story progressed, her family even told her that it was better if she returned to her abusive husband instead of freeing herself from that toxic marriage, because it benefitted others. Essentially, she was to be a lifeless husk of a person and to act as a servant to Harada.
What I think Oseki learns through her run in with Roku is that everyone is going through their own struggles that are equal to, if not greater than one’s own. Roku’s life was basically in shambles when he met Oseki. The significance of this meeting was to show how their separation affected both parties. Their separation is made more evident when Iseki believes herself to be the reason for Roku’s current state of being. Roku thought that he would marry his childhood love, and that dream was promptly shattered when he learned of Oseki’s marriage to Harada. Both of their dreams were.
