Recently, Ji-Hyun is absorbed in reading Kafka’s ‘Metamorphosis’. Her dream is to be a novelist, so she is writing a piece of novel motivated by Kafka’s. The novel is about the biggest loser X, who is becoming an insect-like monster with no reason. There are actually two losers in Ji-Hyun’s class. One is Gi-nam, and the other is Ji-Hyun. Gi-nam is a lot more bullied than Ji-Hyun. Ji-Hyun cannot do anything for Gi-nam except writing her novel, observing him and his bullies. One day, the homeroom teacher gets aware of the class matter because of an anonymous tip. This makes the bullies pick on Ji-Hyun and Gi-nam harder than ever.
