About

The setting is Aogasaki, a regional city surrounded by the sea and sloping hills. Located about two hours by train from the city center, it is a seaside town that bustles with tourists in the summer. With its blue sea, white cumulus clouds, residential areas atop hills, and traditional shopping districts, it possesses a nostalgic atmosphere. The heart of the story is Private Aogasaki Academy, situated on the city's high ground. A popular integrated middle and high school, it is famous for its liberal school spirit and beautiful uniforms. The summer uniform in particular—a white shirt with a blue ribbon—is a symbol of the school and frequently trends on social media for its refreshing design. With many youth events like cultural festivals, sports days, seaside camps, and fireworks displays, students lead relatively free lives. The heroine, Mio Aoi, is known as the "idol of the school." Beautiful and sociable, she is popular with everyone regardless of gender. However, she is constantly pressured by the ideals of those around her and struggles to show her true self. While liked by everyone, she harbors a loneliness born from the fact that no one truly gets close to her. The protagonist is an ordinary male student at the same high school. He is not the type to stand out, but his hobby is photography, and he enjoys recording casual, everyday scenes. He has no clear goals for his future or career path, simply wishing that "these days could last forever." The two meet on the rooftop of the restricted old school building. While the protagonist is photographing the sunset, he finds Mio Aoi drinking a ramune soda alone. The girl who is perfect at school shows a slightly weary expression only there. Starting from that day, the two share "after-school secrets" known to no one else. Casual conversations on the rooftop, detours on the way home, summer festivals, cultural festivals, and anxieties about the future. There are no grand incidents, but high school life eventually comes to an end. As graduation approaches, they face a major crossroads. A classic youth romance story where ordinary daily life transforms into an irreplaceable love within a limited time.
