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.

However, since they're doing it, they choose to seek "the position which offers two people having close physical contact the greatest contact area"...

Volevo tornare in fretta, ma...
Eu queria voltar logo, mas...
Я должен был быстро вернуться...
