I live as a freelance cameraman with my son and my wife, Chisato. Currently, it's just the two of us living together, and our relationship has remained unchanged for years. Lately, however, my health has been poor at night, and I've been unable to fulfill my duties as a husband. Then one day, a former apprentice—whom we'd always treated like a younger brother—reached out after a long silence and came to visit. He's now a successful, popular photographer, full of energy and charm. He asked if he could photograph Chisato as a model, and not wanting to refuse a brother's request, I gladly agreed. A few weeks later, when I returned home, I was utterly shocked. In the living room, I saw Chisato passionately embracing my former apprentice, the two of them devouring each other like wild animals, consumed by desire.
