To attend a friend's wedding...I returned to my hometown during the Obon holiday, and I met my childhood friend Ai, who had also come back to my hometown and whom I had admired since childhood, for the first time in several years. Even though we are both married and have grown up, the smile of love still makes my heart beat faster. When we were little, we decided on a secret sign just the two of us... We secretly sneaked into our love's house and watched fireworks at midnight... Now that we've grown up, we stare at fireworks under the night sky just like we did back then, and can no longer be held back by fireworks alone.
