In a flashback, we see the first time Nanami took Kenji to her field outside the town. Back in the now, Kenji's cousin Hikari is visiting; she is staying there during summer vacation. In the evening the very same day, Kenji, Nanami, Suzuka, Hikari and Hatano enjoy themselves with fireworks. (Source: Wikipedia)
