Two friends, Moon-ho and Jong-kyu, in their mid-thirties now, have known each other since childhood. As time passes, they feel more and more sorry of their younger years.

Moon-ho finds Yun-jung through the internet to have an extramarital sexual affair. Jong-kyu goes out with his first love, Soo-hyun, for the first time in ten years and together they head for a hotel... But the story goes on as if the two couples had never met...
