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...
Am I afraid something might 
have happened between them?
أأخاف أنّ شيئًا ما قد دار بينهما؟
Ich habe so viel Angst,
dass zwischen den beiden etwas war …
Tengo miedo de que haya pasado
algo entre ellos.
Tengo miedo de que haya pasado
algo entre ellos.
L’idée qu’il se soit passé
un truc entre eux me terrifie.
Sono davvero preoccupato
 che possa essere successo qualcosa fra di loro?
Estou com medo de que algo
tenha acontecido entre os dois?
Неужели я правда боюсь, что
между ними могло что-то произойти?
