Elementary school student Seon is regularly bullied and when she is left alone in the classroom on the last day of term, she meets a transfer student named Jia. They become close through sharing their secrets and spend the whole summer vacation together. But when the new term starts, Jia starts giving Seon the cold shoulder. Seon does her best to restore the relationship she had with Jia but their situation gets worse. After the short and happy time with Jia, the school soon becomes hell again for Seon. Grown-ups happily say, “Children don’t have any problems…” but relationships are not easy, even for elementary school students; they get hurt more easily and suffer more deeply. <I>THE WORLD OF US</I> scrutinizes the small society of elementary school. There are plenty of movies and TV dramas touching on the issue of bullying, but none has as quite as intense a portrayal as <I>THE WORLD OF US</I> does. The director’s gaze attempts to delve into the reality in order to evoke viewer sympathy.
