Tamako is 20 years old, lives at home with her mother (Kishimoto Kayoko) and teenaged brother, and simply refuses to grow up. Ever since her father left the family, she's stopped trusting people, and now lounges around in her own small, claustrophobic world. Wearing an iron helmet whenever she steps outside, she ventures only to her mom's beauty salon, the mechanic shop, and the bakery - the source of her greatest joy in life, sweet buns. Her world is static, insular, and safe, and there's no need to change - that is until her cat runs away, the bakery closes, and her mom falls in love with another man.

Umi’s hearing is so sensitive that even notes played slightly out-of-tune give her a headache. Violinist Yuko arrives from Tokyo to play a concert on Umi’s small island near Okinawa, and gradually befriends the girl. Both struggle with friendships and family relationships, but are brought together by music.

Twenty-something lesbian Chinatsu shares a one-bedroom apartment with heterosexual Kyoko. Although Chinatsu and Kyoko have a passing attraction, Kyoko is mostly interested in men, especially one who tends the fish in a pet store, who despite her efforts, doesn't seem to be interested in her.
