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. The two have dinner and talk about
the old days, especially an old friend, Chul who used to stand up to The
Dogs. Every time one of the Pigs was targeted Chul would retaliate a hundred fold. He had nothing but contempt for the Dogs and embraced his
low social standing in society. Chul promised to always punish those that
lorded over the weak with each act becoming crueller and crueller.

After fifteen years what has become of Chul?
