On days when he can get home early, he heads over to Sensei's house, where he is used to visiting, with a bit of excitement, to spend some sweet time alone together outside of work. Their days are filled with a sense of relief and fulfillment that comes with being two people of a certain age. However, Nakai's heart still races when Sensei suddenly becomes affectionate, and they get aroused when they smoke the same brand of cigarettes, and there are still bittersweet, exciting days...?
