Kim Minseok was just a ordinary good boy. Good grades, nice attitude, friendly with everyone he meets, and maybe he might be the most innocent person in the entire world. He's in his first year of high school for goodness sakes! Kim Jongdae or how he wants everybody to call him, Chen, is just your typical bad boy. Has the worst grades, bullies other students, a playboy, and a jock. He rides a motorcycle to school, and skateboards on other people's property. One Monday morning, he sees a small kid in front of the school holding a ton of books, big thin, circular glasses, and trying to get his way in, and Chen here decides to 'help' him a bit.
