This film is based on the novel "Meet in the Rainy Season" by Takuji Ichikawa, starring So Ji-sub and Son Ye-jin. It tells the story of a man (played by So Ji-sub) whose wife Soo-ya (played by Son Ye-jin) told him before she died that she would come back in the next rainy season. Sure enough, when the rainy season came, his wife came as promised. But strangely, his wife seemed to have forgotten him and his family.
