At the end of the summer break, right after finishing final exams, I finally welcome the long-awaited freedom of summer vacation. Returning home to my hometown for the first time in a while, I run into Aoi-chan, my childhood friend, on the train station platform. She used to live nearby, and when we were kids, we always held hands walking to school. Seeing her again after so long, I notice she's grown more mature—and even cuter than before. My long-forgotten first love stirs in my heart. Strangely, she starts making bold moves toward me. Whenever I try to confess, she mischievously smiles and turns away, dodging my words. In her attitude, I sense a sweet yet malicious charm. An unusual connection begins to bloom between us as summer draws to a close.
