a pungent smell that stings the nose. the source of the smell filling the living room was his mother, Yuko, sleeping on the sofa. "sleeping here again..." Yuko, who often comes home tired from her recently started part-time job. if she continues to sleep on the sofa like this, she will catch a cold. the son, who approached to carry her to the bedroom, had his nasal cavity brushed by the rich scent of sweat. "just a little more... is it okay if i keep sniffing, mom?" i don't want to leave this fragrant smell. suddenly driven by a strong impulse, the son brings his face closer to Yuko's wet armpit.
