A boy gets asked to run away. The entire film holds its breath around that one question, turning a single summer day into something that feels like it could break the world. The animation doesn't just show you fireworks, it shows you what it feels like to want something so badly you'd risk everything, and then the ending pulls the rug out in a way that rewrites what you thought you were watching. The plot gets messy, the characters stay thin, but none of that matters once you understand what the movie is actually doing with your chest.
On the last day of summer vacation, a group of middle schoolers chases an impossible question: do fireworks look round or flat when you view them from the side? The answer seems to matter more than it should, pulling them toward the town lighthouse as evening falls. But Norimichi's world tilts when Nazuna, the girl he's quietly watched all summer, finds him alone and asks him to disappear with her. She's serious. She wants to leave town tonight, and she's chosen him. What follows is a single night that bends between reality and something stranger, where a simple choice spirals into consequences that reshape everything. The film moves with the hazy logic of a dream, mixing the genuine awkwardness of adolescent attraction with moments that feel almost supernatural. Summer air hangs thick throughout. The tone shifts between wistful and eerie, between the sweetness of a first real connection and the weight of decisions made in darkness. It's for people who remember how enormous small moments felt as kids, and who recognize that some nights change the shape of your whole life.
