Since childhood, Nana and I had always been together. We were more than just childhood friends—we shared a deeper bond. But I kept my feelings hidden for so long. Today, I finally wanted to tell her: "I love you, Nana." At last, she became my first girlfriend. Every moment with her felt extraordinary. I dreamed of taking her on dates, but we lived in a rural town with no convenience stores or game centers. In that isolated environment, our only pleasure was sex.
