Rika, a married woman who has been married to her husband for three years. Her husband has become busier than when she first got married, and she now receives almost no attention. Rika, who felt her loneliness about that, persuaded her husband that she could just take a walk, but she didn't take it. She took out this morning's leaflet and handed me a guide to a swimming class that she could go to if she had time. Rika decides to go to a swimming class even though she feels shocked by the couple's passing. She has no way of knowing that her decision will upset her marital relationship.
