It was a muggy midsummer day. "Mom, you'll catch a cold if you sleep here," said Yuu, who had been working non-stop at the supermarket and often ended up sleeping on the sofa. Concerned about the tired Yuu, Haruo, her son, approached to move her to the bedroom, but was assailed by a stimulating scent that tickled his nostrils. "What is this smell..." A fragrant scent of sweat that seemed to appeal directly to his instincts. He wanted to smell the rich aroma up close. Captivated by his desire, Haruo began to aggressively seek out the source of the scent, pressing closer to Yuu.
