Reiko runs into Mayu and Yuki who came over to study with Chie and notices something unusual with Yuki’s body. Yuki, who is still developing, is not wearing the correct size bra.
Chie and Mayu watch indifferently as the two share their pain of having a large chest.
When they sway, 
they're heavy and painful.
عندما يتأرجحان يكونان ثقيلين ومؤلمين
Wenn sie sich bewegen,
sind sie schwer und schmerzhaft.
et les garçons 
se moquent de moi à la gym !
Quando corro, pesano e fanno male.
Quando balança, são pesados e doloridos.
