O-Negative

Overview

A group of five teenagers of the same blood-type 'O' become friends at art college. Prim has a crush on bad boy Art, while her friend Foon likes quiet Puen. The five form a band and survive freshman initiation rituals, but conflict erupts when romances break up the group's harmony.
