We live in an awful world, where the haves have everything, and the have-nots lose all. We feel terrible, depressed and angry about that, always looking for the hero who would solve all of our problems. Perhaps we just lost our self-confidence and hope to dump all of our problems on someone else. But if that hero existed, he would be like us.

It’s been fifteen years since Jong-suk and Kyung-min, two high school friends, have seen each other. Both grew up poor and weak, constantly being picked on by others. The school they attended had the students separated into two factions, The Dogs, who were the richer, well to do, popular kids while the poor and scrawny kids were known as The Pigs. Jong-suk and Kyung-min were Pigs.
