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"...
How could I forget this? 
I'm never gonna forget.
.كيف يمكنني نسيان ذلك؟ لن أنسى هذا أبدًا
Wie könnte ich das vergessen?
Nie im Leben!
¿Cómo podría? No lo olvidaré.
¿Cómo quieres que lo olvide?
No lo olvidaré.
Alors ça,
ça restera ancré dans ma mémoire !
Come potrei dimenticarlo? Non accadrà mai.
Não vou esquecer isso.
Não tem como esquecer.
Как мне такое забыть? 
Я всегда буду это помнить.
