Olivia, a foreign transfer student who doesn't speak English, engages in a game of "look-the-other-way" with Hanako Honda, a loudmouthed airhead, during break. Kasumi Nomura, a deadpan loner who is regularly taunted by her older sister for her tendency to lose games, is enraged by their boisterous conduct. Kasumi resists Olivia's invitation to join the fun because she is unwilling to compete, but she finally joins in and causes her own brand of mayhem. Soon, the weird trio forms a strange camaraderie, and they decide to join the "Pastime Club," where they may repeat their regular antics. Whether it's failing to learn English, attempting to become popular desperately, or being caught by teachers at the wrong time, school life will never be dull when the students are involved.
