Stuck with the bad boy in a desert island

Harmony Stone. The weird girl that eats in the soccer field with her friend. The weird girl with blue hair that sleeps in the sciense lab after school. That same girl got stuck with the meanest and rudest guy in the whole campus.
Tom Blue. The hottest guy in the campus. Capitan of the soccer team. Enjoys drawing but no one actually knows. That same boy got stuck with the antisocial girl.

What will happen when this two people get stuck in a desert island?
