we are presented with a bored, cynical, and generally unsociable male protagonist who is largely uninvolved with his high school life until his encounter with the eccentric female protagonist.
Initially, both protagonists are reluctant to help, but continue to find themselves becoming more and more involved and even attached to the people he made friends with.
