On the night of the fireworks festival, August 26th, we, who had been secretly in love for many years, finally reunited. We devoured each other's bodies, as if pouring out over a decade of love. (Hebei Caijia, SONE-853)

Ayaka and Kenichi have been close since childhood. Ayaka stayed in their hometown, while Kenichi moved to Tokyo for work. After their coming-of-age ceremony, they reunite, both noticing each other's presence and feeling a pang of longing. This is because, with the onset of puberty, they begin to see each other as members of the opposite sex… However, to avoid breaking their friendship, as they grow older, they distance themselves and no longer express their feelings. This is their first reunion after so long. A fireworks display that stirs their hearts. How will this unrequited love ultimately end?
