It's Always That in August (S01E08)

The summer festival arrives, marking the one day Keita can escape his prep school obligations. Excitedly, Ako and Riko both vie for his attention throughout the night, even as they enjoy the festival together. However, a series of events involving parade participants allows Ako and Riko to steal some moments alone with Keita. Complicating matters is Kiryu-sensei, who is patrolling the event and surprises Riko and Keita in a forested area. Then there’s Mikazuki, the Miss Mikoshi, and a mischievous chick Ako brought along, leading to an awkward encounter where Keita catches Miharu in an embarrassing moment, causing her to drop what appears to be a love letter.
