Won-Deuk (Yoo Ah-In) is a sophomore in high school with a miserable
outlook on life. He doesn't have much interest in school, his diminutive
size father has a hunchback and Won-Deuk doesn't know anything about
his mother. The one thing that Won-Deuk excels at is fighting. Although
he isn't aggressive by nature, If anybody makes a snide comment about
his father then Won-Deuk has no problems beating the crap out of them.
Making Won-Deuk's life that much more miserable is his homeroom teacher
Dong-Joo (Kim Yun-Seok) who seems to frequently pick on him in class.
This bothers Won-Deuk enough that he often prays in ch11urch for
Dong-Joo's sudden death. If Won-Deuk doesn't get enough of his homeroom

lives in the apartment directly in front of the parked car did it.
Dong-Joo yells at the man from the street to come out and then demands
an apology. Instead of apologizing the neighbor curses at Won-Deuk's
father. Before anybody can do anything, Won-Deuk punches the neighbor in
the face. They all go to the police station.
At the police station, Dong-Joo stands up for Won-Deuk and attempts to
shield him for any type of punishment. The neighbor is still persistant
in getting charges filed, but his sister Ho-Jung (Park Hyo-Joo)
apologizes for her brother's behavior and brings the matter to a close.
Meanwhile, homeroom teacher Dong-Joo becomes attracted to his neighbor's
sister. Won-Deuk also begins to view his homeroom teacher in a
