He loves the stuffy smell of sweat, making his workplace a real piece of heaven. Then, one day, he smells the scent of a scaffold worker on the site, Kagawa, and gets hard...!? Unable to bear with it, he going to the toilet to take care of it, but the guy himself shows up and declares "I got the urge to do you."
