During art class, a scandal erupted when homeroom teacher Mr. Yama-gishi was fired for touching the female model. Amid the laughter of the delinquent group, my attention was completely captured by the temporary teacher, Eriko Miura, who had just arrived. Her seductive smile, tight skirt, and low-cut blouse deeply stirred my emotions. Entranced by her appearance, I found myself sketching Eriko Miura's figure during class instead of the assigned subject—and was eventually caught by her. After school, I was summoned to an empty library and told to wait for her there.
