Three years into marriage, Ayaka and her husband do little but argue, and their sex life has completely disappeared. Lonely and reluctant to go home, she begins spending evenings at a comfortable little bar run alone by Ozawa. Just when she thinks she may be ready to forgive her husband, she discovers his affair. Devastated, she returns to the bar and begs Ozawa to make her forget him, beginning a series of intimate late-night encounters.
