Summer vacation is over, and the Aozora Cultural Festival is approaching; after things went well with Mami at the fireworks display, Towa is delighted to be spending more time with her preparing for the festival.

Towa and Mami are steadily growing closer, but they both have concerns about their families; Towa is having trouble with his relationship with his mother, and Mami remains unable to tell her family about her relationship with Towa.

Miharu is scheduled to take time off from school and transfers to another hospital for surgery; she feels both anxious about the upcoming procedure and sad to be moving away from her friends.
