The summer air is thick with nostalgia as the story unfolds in a quiet town, where memories of youth linger in every corner. A woman, known as "Sai-ka," is greeted by her old friend, "Kei-ji," who returns to town after years apart. The conversation takes a warm, familiar turn, bringing back the memories of long summer vacations and lively festivals. As they reminisce, the topic of the fireworks festival comes up, setting the stage for a rekindling of old feelings. Kei-ji, who has been away in Tokyo, shares a gift with Sai-ka, a small token of his return, and the two are soon joined by "Ken-ichi-kun," a boy who has been in the background of Sai-ka’s life, quietly watching from afar.
Ken-ichi-kun, who has been staying with Sai-ka’s mother, is introduced as a kind and gentle presence, someone who has been waiting for a chance to speak his heart. As the night unfolds, the three of them gather in the living room, where laughter and light from the fireworks outside blend into a warm, intimate setting. Sai-ka’s mother, ever the matchmaker, encourages the two young people to take the next step, and the tension between them slowly gives way to a moment of confession. Ken-ichi-kun finally gathers the courage to tell Sai-ka how he has felt for so long, and the moment is both emotional and liberating.
As the night deepens, the fireworks light up the sky, reflecting the glow of newfound love and shared dreams. Ken-ichi-kun and Sai-ka’s connection grows stronger, and with a final, heartfelt moment, they both take a step toward a future together. The story closes with a sense of renewal, as Sai-ka and Ken-ichi-kun look forward to a new chapter, no longer holding back their feelings.
