Junichi, the nephew who had admired his young and beautiful aunt Rei, came to her house with a made-up reason. He wanted to see his aunt for one reason and another... he wanted to see his aunt's "underwear." In the bathroom, there was freshly worn underwear left unguarded, and Junichi was secretly rummaging through it. However, Junichi became so engrossed in the underwear that he was eventually caught, and asked, "Do you really want to see your aunt's underwear?"
