Nanako Usami is a first year high school student living in the country town Nagarekawa.
Just as she starts getting used to high school life, she makes plans to visit the public pool with her friends after its renovation.
While she begs her mother for a new swimsuit for the special event, her mother refuses her flatly.
I bet you'll say my breasts are too small.
.أراهن على أنك ستقول أن حجم صدري صغير
Du willst sicher sagen, dass meine Brüste zu klein sind.
Apostaría a que dirás que 
mi busto es muy pequeño.
Seguro que me vas a decir
que tengo muy poco pecho.
Tu veux dire que je manque
de poitrine, c’est ça ?
Eu aposto que você vai falar que 
meus peitos são muito pequenos...
