Shark: Wyvern

"Don't brag about your money in Yeosu, your looks in Suncheon, or your fist in Boseong." There is an old saying like this, but there was a guy named Hyun Woo-yong who completely defied the warning against boasting about fists in Boseong. He was an 18-year-old high school student. Hyun Woo-yong, who had beaten up not only the delinquents at school but also the gangsters who backed them, ended up getting arrested for causing serious injuries. He served two years in the notorious "True Light Juvenile Detention Center" and was released. Afterward, he headed to Seoul. At the age of 21, Woo-yong returned to high school as a second-year student with a single goal in mind: to graduate high school safely and receive his diploma. However, contrary to expectations that it would be an ordinary liberal arts high school, Hanyang High School was a place filled with all sorts of school violence and unfair practices. Initially, Woo-yong tried to live quietly and endure everything, promising himself to stay composed. However, the actions of the ruthless bullies pushed him to change his mind.
