On their second anniversary of marriage, Kang Nam-dae and Jang Young-mi get bored with their routine sex. They visit a motel to re-live their first night and record it on a video camera. Nam-dae spoils the moment by bringing up their mutual friend Jae-guk whom Young-mi had dated previously. After reading Jae-guk's book and realizing he truly loved her, she leaves Nam-dae. Two years later, they meet again and go to see Jae-guk.
