Miku Sumida, a married woman, was walking through the city when she was approached by an unpopular guy who claims to be highly potent yet suffers from premature ejaculation. "Please help me—I'm virile but can't last long, and it's why I'm not popular with women!" he pleads, hitting on her. As she sincerely listens and offers advice, she gradually begins to feel a rising desire. Drawn to his intense stamina, she boldly initiates intimacy inside a car, rapidly deepening their connection. The passion between them ignites with a force stronger than love at first sight.
