After resolving their quarrel, it seemed that Adachi and Shimamura had returned to their original relationship. However, Adachi's feelings for Shimamura wouldn't allow her to be satisfied with the status quo; instead of being swept along, she was determined to move forward on her own. "Shimamura, let's hang out!" "Huh, no way. I'm going to my grandpa's house for Obon." "Oh, I see... How many nights?" "It's planned for three nights and four days." "Then, then. Can I come back in four days...?" "Ah, okay. I'll call you when I get back." "I'll be waiting." Unable to contain her excitement, Adachi reaches out to Shimamura through phone calls and messages. In response to this, Shimamura's feelings for Adachi begin to change as well. Then comes the night of the fireworks festival. Dressed in yukata, the two walk through the bustling festival atmosphere. Adachi's feelings for Shimamura soar high along with the fireworks.
