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...
I'm not just concerned as her best friend, 
but also as someone's little sister.
،لستُ قلقةً بصفتي صديقتها العزيزة فحسب
.بل كشقيقة أحدهم الصّغيرة أيضًا
Es liegt nicht nur daran,
weil ich ihre beste Freundin bin …
No solo como su amiga.
No solo como su amiga.
Ça me dérange
en tant que meilleure amie,
Non sono preoccupata solo in qualità 
di migliore amica, ma anche di sorella minore.
Mas não é apenas curiosidade como melhor
amiga, é também como uma irmã mais nova.
Я переживаю не только как лучшая
подруга, но и как младшая сестра.
