My son lost his rationality due to the smell of sweat that sniffed his mother's throbbing sweat after he returned from his part-time job.

Mio, a mother, started working part-time to earn money for her son's tuition, has been sleeping more and more on the sofa. If things continue like this, I'll catch a cold. A sweet and sour smell tickles my son's nose as he approaches to bring Mio to his bedroom. "What is this..." The moment I sniffed, I realized that my body was getting hot as if I was holding it in my hand. I want to smell a deeper smell. Moved by an impulse, the son delves into the sweaty body hidden under his sweaty clothes in search of the source of the scent.
