The neighbor, Mr. Miyashita, became the source of constant frustration for my wife due to his poor manners. Smoking in shared areas and repeatedly violating garbage disposal rules drove my obsessively neat and etiquette-conscious wife to her limits. I, valuing peace above all, tried to tolerate him despite his unpleasant nature—until one day, when my wife, acting as the head of the local women's association, visited his apartment with a petition. That incident triggered an unexpected turn of events.
