The girls work on summer homework and Futaba comes over. She's nervous about telling her friend that she likes fishing, so they come up with a plan to see if she should tell her friend or not. Later on, the girls go fly fishing at a mountain stream.
Basically, they're fish that haven't
been caught yet, so their guard is down.
.إنّها ببساطة أسماك لم يتمّ الإمساك بها من قبل، لذا فهي غير حذرة
Fische, die noch nie aus dem Wasser gezogen
wurden und entsprechend unvorsichtig sind.
Nunca los han pescado
y por eso no desconfían tanto.
Ils n’ont jamais été pêchés,
donc ils sont peu vigilants.
Dei pesci che non hanno mai abboccato a un'esca
 e non hanno nessuna diffidenza.
Ninguém os fisgou, e não têm tanto medo.
