Ikumi works at a luxury soapland, where brief skin-to-skin encounters offer relief from her distant marriage. One day, a younger adult man named Sugiura arrives—a sweet former coworker from ten years earlier. He does not seem to recognize her, but Ikumi gradually stops treating him as just another client and responds as a woman. As their hot saliva and tongues mingle in deep kisses, the feelings she buried a decade ago come rushing back.
