One cold winter’s day, Euno was caught red-handed while trying to steal from a man who had entered the mountain, and ended up being severely punished. Terrified for his life, Euno begged the frightening man—crying and promising to do anything—just to be spared. From that day on, he was taken by the man and forced into servitude… Chaeyoon, who despises the world, and Euno, who knows nothing about it. From a chance encounter on Mount Moak to the fate that follows. Their story through winter, spring, summer, autumn— and then back again to winter.
