SONE-853 August 26, Fireworks Night. We, who had secretly loved each other for years, finally came together and embraced each other with all the feelings we had kept inside over the years. Kawakita Saika

Ayaka and Kenichi had been close friends since childhood. Ayaka stayed in their hometown, while Kenichi moved to Tokyo after getting a job.

When they reunited for the first time since their coming-of-age ceremony, they felt a sense of nostalgia and also became aware of each other once again. As they grew into their teens, they had started to see each other as the opposite sex. However, neither of them wanted to risk losing their friendship, so they never confessed their feelings. They grew up, and before they knew it, they had drifted apart.

Now they were spending time together again after a long while. A fireworks festival stirred up their emotions. What will become of these two who secretly shared mutual feelings?
