The final festival of high school!
About
Six friends who became close during a group activity in their third year of middle school. By chance, they all ended up at the same high school and have spent every moment together from their freshman to senior years. Gathering after school to talk about nothing, hanging out on weekends... before they knew it, being together as a group of six became their normal. It is summer. The summer break of their senior year is coming to an end, and the time to think about their paths after graduation has arrived. One day, the six gather for their annual summer festival. Wearing yukatas, browsing the stalls, eating street food, and watching the fireworks. It was supposed to be just another fun day like always. But this year felt a little different. The last summer of high school. From next year, they might all be walking different paths. The daily life of these six, which they thought would last forever, was nearing its end. This is the story of the final summer festival spent by six friends on the verge of graduation. The times they laughed together, the words they couldn't say, and the secret crushes held in their hearts. Like fireworks blooming in the night sky, a short but unforgettable day of youth begins.
