After two years of marriage, they are not on bad terms, but Sumire feels lonely because of her husband's indifference. When I was worried about getting someone to turn around somehow, my father-in-law, Kazuo, gave me a consultation. However, her husband is indifferent no matter how much he invites her, and on the contrary, Kazuo can't take his eyes off her. And Kazuo, who couldn't stand it while encouraging the disappointed Sumire... From that day onwards, the two continue their relationship while stealing their husband's eyes. Sumire is looking for a son of her father-in-law, not her husband.
