Maki Hojo lived happily with her husband. However, after he lost his job, he turned to drinking and gambling, gradually spiraling into self-destruction. When in a bad mood, he began to physically abuse Maki. Driven to despair, she decided to leave home—but realizing she needed income to survive, she resolved to start working part-time. One day, she found an article titled "The Urban Legend of the Yellow Panties" in a magazine her husband had touched. Skeptical but curious, she decided to try it. She hung a yellow pair of panties on the clothesline of her balcony, and soon a man arrived, asking for her assistance. As a result, she easily earned 30,000 yen in cash. From that moment on, Maki began attracting more and more clients, quickly turning it into a highly profitable venture.
