In an innovative and touching manner, the story of an ordinary high school boy and his troubles is narrated through Punch. He's poor with a disabled father and no mother. He's bad at his studies. Has no dreams. Only knows how to fight and has a strict teacher. Terrible enough for an 18-year old boy. The film is about this boy's journey to grow up with the help of the adults around him. He grows and they do. Excellent acting of everyone. Beautiful Yoo Ah In as usual. Hilarious. Touching. And the most beautiful story of a student/teacher relationship.
