"Everyone is the protagonist of their own life story." In Class 2-1 of a certain girls' school, with an average偏差値, 30 unique students spend their days in a lively and chaotic atmosphere that never gets boring. As summer vacation approaches, the classroom feels a bit restless. The whole class is buzzing with discussions about what to do during the break. Some are planning trips to the pool or ghost hunting, while others are still dedicated to their club activities... Even the energy-saving girl and the serious class president seem to be taking small steps towards each other in the summer air. A heartwarming conclusion to the school-themed omnibus, watching over this uniquely "yuri-filled" class!
