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 can't get it out of my head...
...لا يمكنني إخراجها من رأسي
Ich krieg das nicht aus meinem Kopf.
Jamás podría olvidarla...
Jamás podría olvidarla...
Impossible d’oublier cette mélodie,
Aquilo não sai da minha cabeça...
