There’s an old saying: ‘Don’t brag about your money in Yeosu, who you are in Suncheol, or your strength in Beolgyo.’ However, there was a boy who completely ignored the warning against bragging about strength in Beolgyo. He was an 18-year-old high school student named Hyun Wooyoung. After spending two years in the notorious ‘True Light Juvenile Detention Center,’ he returned to high school at the age of 21, trying to graduate like any other normal student. However, in a place filled with school violence and all kinds of injustices, his patience reached its breaking point.
