Kimi to Hanabi to Yakusoku to

君と花火と約束と

The coming-of-age romance is set during the Nagaoka Festival Grand Fireworks Show, one of Japan's three major fireworks shows that draws several hundred thousand visitors to Niigata Prefecture every year. What connects Makoto (a Tokyo high school boy without social skills or self-confidence) and Aki (a popular high school girl and class president with beauty and talent) is a drawing of a fireworks display. At the mercy of the drawing's mystery and fate itself, the two have to make a choice in a limited amount of time.
