In the quiet town of Hoshimachi, where fireflies dance in the summer dusk, Ren Takahashi dreams of leaving of escaping the small streets and fading sunsets for a life beyond the horizon. But when he meets Hikari Tanaka, a girl who sees beauty in every fleeting moment, his world begins to shift. She hums softly when she’s happy, spins in the summer breeze, and believes that some things—no matter how brief—are worth cherishing. As the fireflies return each summer, so do the memories they create. But like all beautiful things, summers don’t last forever. A story about love, longing, and the warmth of a distant summer that never truly fades.
