Covered from head to toe in black, the invaders grab HyeJa and make a run for it.

Watching the tail lights disappearing into the snow flurry, his master abducted, the dog’s anguish beckons a God’s mercy. Being given an opportunity to get the woman back, he is turned into a human. However, there are strict conditions and the ultimate price to pay for his chance.
