As Ichika is pondering on what Tetsurō told Kaito that night, thanks to Tetsurō's sister, filming for their movie goes to Okinawa, where Kaito meets a childhood friend, and Tetsurō is found pleasing by her companion. This puts Kanna and Ichika at an unease, especially when Kaori, the girl, says that Kaito is her fiance. Miu, on the other hand, is uneasy herself when Chiharu, Kaori's companion, sets her sights on Tetsurō.
