After three years of marriage, Eimi was living a happy but unsatisfactory life. One day, when she lost her house key and was at a loss, she was asked to wait in the room of her withdrawn neighbor, Sakuta. Sakuta, who was secretly eavesdropping on her neighbor's house, revealed that she was unsatisfied with her husband and was chronically frustrated with her, and forcibly pushed her down. Despite her resistance, Eimi remembers the pleasure she once felt from the intense stimulation she felt for the first time in a long time.
