Far from campus and struggling financially, college student Kenta lives alone in a cheap apartment with no room for comfort. He begins receiving meals and daily necessities from his neighbors, the Nomoto family, and though grateful, he gradually grows closer to them. One day, the bicycle he received from the Nomotos breaks down, so he asks for help repairing it. When the wife, Kyoka, inspects it, his life takes a sharp turn. Kenta discovers Kyoka isn't wearing panties—and from that moment, his emotions spiral out of control. Her bold, pantyless presence shocks him deeply, transforming his everyday reality. Meanwhile, Kyoka teases him with provocative behavior, seemingly mocking his feelings, leaving Kenta increasingly confused and aroused.
