“I’ve come to be your girlfriend” On a humid night just before summer vacation, a silver-haired, red-eyed girl suddenly appears. The protagonist, Mihoshi Kanata, who lives with his lively older sister, experiences an “unusual” life. The mysterious girl, who calls herself “kami”, has shown her affection for some reason since the first time they met. She is unashamedly straightforward and reckless. Every day spent with this mysterious girl is filled with laughter. Under the same roof. Helping people, playing at the beach, eating delicious food together. We’ve always been together. I wished these peaceful days would continue forever. I never thought the day would come when I would shed so many tears in exchange for love. An emotion I’d never known before. A hopeless, frustrating feeling. The world changes when you experience the girl’s kindness. An unforgettable summer begins.
