Shimoyama, a teacher, returns to Amayadori, an izakaya known for winning over working men with its food and welcoming atmosphere. Ever since he first wandered inside, his heated gaze has been fixed not on the dishes but on the young proprietress, Ririko. Crushed when he learns she is married, he drinks himself into a stupor and falls asleep in the bar. When he wakes after closing, Ririko is sitting beside him in the dim room with a smile. What follows is an intense night of forbidden, condomless sex drenched in her juices.
