After failing college entrance exams three times, I began taking private tutoring from Mio Kimijima, my brother's wife, who graduated from a top university—on top of my regular cram school classes. She was kind, intelligent, and possessed a strikingly voluptuous charm that I secretly admired. One day, during a direct hit from a powerful typhoon, Mio came over to tutor me, drenched from head to toe. In the midst of the storm, her hair glistened with moisture, and her clothes clung to her body, revealing every sensual curve. Mesmerized by her appearance, my suppressed desire spiraled out of control.
