Sweet

One cold winter day, Eun-Oh gets caught robbing a man who came into the mountains and gets beaten up. Eun-Oh cries and begs the man to spare his life, saying he'll do anything for him. But that very day, he's captured by the man and forced into slavery... Chae Yun-Sa, who finds the world repulsive, and Eun-Oh, who knows nothing about it. The story of how a coincidence on Mount Moak becomes inevitability. Their winter, spring, summer, fall, and back to winter.
