Now officially a couple, Kazehaya and Sawako go on their first real date. Over summer vacation, Sawako asks Chizu and Ayane for relationship advice.

With the class trip coming up, another boy approaches Ayane. When the students arrive in Okinawa, the new atmosphere causes big changes in everyone.

Sawako feels like Kazehaya is keeping his distance. After connecting with Ryu on the trip, Chizu tells her friends about her memories with him.

After his teacher gives him some advice, Kazehaya finally talks to Sawako on their way home. The next day, everyone gathers at Sawako's house.
