Episode Context

Following the Okinawa trip told from Iori and Chisa's side in the previous installment, this finale shifts to Aina and Kohei's view of the same outing, reframing the earlier episode's suspicious background details as part of their meddling. The season then closes on the romantic tension that scheme leaves behind, setting up the next round of complications for Iori and Chisa.
