Plot
At a live concert, In-su (Bae Yong-jun), alighting director, hastily hands over his duties to a junior staff member and exits the concert hall quickly. Outside an operating room at a hospital in the seaside town of Samchuk, Gangwon province, In-su finds Seo-young (Son Ye-jin): his hasty trip had been due to a car accident involving Su-jin (Lim Sang-hyo), and Seo-young's husband, Kyong-ho (Ryu Seung-su), was riding in the same car. Seriously wounded, Su-jin and Kyong-ho have not regained consciousness. In-su and Seo-young gradually finds out about Su-jin and Kyong-ho's special relationship: the fact that their spouses were cheating on them is somehow worse to accept than the terrible accident. While the two betrayed spouses blame their injured partners, at the same time wishing for them wake up again, they gradually begin to feel something towards one another. As In-su and Seo-young are staying at the same motel in front of the hospital, they start to see a lot of each other. And as they spend more time together, they begin to fall in love with each other. The roles then become reversed; the two who had previously been cheated upon are now cheating in the same way, sharing the same pain and betraying their spouses. When Su-jin finally wakes up, In-su can't neglect his wife, who now regrets her past actions. Watching him, Seo-young realizes that it is time to return home. The two prepare to go on a trip of their own, which might be the last chance for their relationship...
