Ichika and Rio go to Okinawa for a school trip. Masuda ends up coming along with one of his seniors at work to be their camera guy on their trip. Rio had been sending pictures to Ryo from their trip, which ends up reminding Ryo of Kai and he gets worried. Meanwhile, Ryo ends up picking up an anime keychain that his coworker Matsushima Arie had dropped and she asks him to not let anyone at work know about her hobbies, and he has something nice to say in return...
Also, if you wanted to know if Masuda-san 
was here, why didn't you just call Rio?
وإن كنتَ تريد التّأكّد من تواجد
ماسودا-سان، فلمَ لم تتّصل بريو؟
Aber hättest du nicht Rio fragen können,
Y podrías haber comprobado lo de Masuda
Y podrías haber comprobado lo de Masuda
Au fait, si vous vouliez vérifier
pour Masuda,
Inoltre, se volevi sapere se Masuda fosse qui, 
perché non hai chiamato Rio?
Aliás, se quer confirmar algo do Masuda-san,
não era melhor ligar para a Rio?
И если вы хотели узнать, правда ли
Масуда здесь, почему не позвонили Рио?
