Ep. 6: Reflecting on beach trip while Chiaki retaliates against Kana's pranks

6

Uchida and Yoshino fondly recall a beach day that began with Kana suffering from motion sickness. Yoshino observes that Chiaki views Fujioka as an older sibling, similar to Kana’s bond with Uchida. The memory is interrupted when Chiaki searches for her teddy bear, which Fujioka retrieves while Kana hides her involvement. Maki uses Fujioka’s calculations to avoid summer homework until Kana and Chiaki stop her schemes. Later, Uchida struggles with homework without Chiaki’s help, realizing her dependence is mutual after Makoto demonstrates this dynamic. Finally, Chiaki avenges past pranks by eating both her own dinner and Kana’s, thwarting Kana’s attempts to delay the arrival of autumn.
