At long last, it's the first day of the summer training camp. On the plane, Yukimura presses close to Himuro and tries to collect her saliva in spite of the surrounding gazes. Manga artist Yamamoto observes them with an eerie smile. On the beach in Okinawa, the midsummer sun shines down on Yukimura and Himuro in their swimsuits, and they immediately attempt to begin their close physical contact experiment. However, since they're doing it, they choose to seek "the position which offers two people having close physical contact the greatest contact area"...
Memories of experiences where emotions 
are involved can't be forgotten.

Las experiencias con emociones
involucradas no pueden olvidarse.
Je n’oublie jamais
les émotions que j’ai eues.

não podem ser esquecidas.
События, связанные с эмоциями, 
забыть невозможно.
