Yurim (Lead) An innocent yet determined younger sister who steals oil in a dystopian environment to bring her family back together.

Juna (Lead) A second-generation Korean-American girl. Due to her parents’ circumstances, she suddenly goes to live with her grandmother in the countryside. Having had little contact with her grandmother and facing a very different culture, she seeks out familial love as they navigate a challenging life together.

Young Noah (Supporting Role) A young Noah whose emotional expression is more important than dialogue, portraying the reasons behind the choices made by the adult Noah.

Young Seoyul (Lead) A child living through a grueling schedule in Daechi-dong, seemingly gaslighted by her mother. Watching the goldfish trapped in a fishbowl, she compares it to herself. Playing the role of an eight-year-old—much younger than her actual age—this performance centers on facial expressions and emotion.
