- Confectionary salesperson Kanako (Takeuchi Yuko) is busy trying to organise the "Love Fireworks" for the shopping street's Firework festival, which traditionally opens and closes the festival. Legend has it that the "Love Fireworks" can bless lovers with lifelong happiness, and Takimoto is the only firework master that can operate it. However, since an accident, Takimoto has given up on fireworks. Kanako found Takimoto in hopes to persuade him to operate it again. At the same time, pianist Kenta (Tamayama Tetsuji) finds himself in heaven even though he is still alive, and is working at the Heaven's Bookshop. One day at work, he sees his idol pianist Shoko (Tamayami Tetsuyi). However, something that happened made Shoko unable to play the piano. The two stories unfold in two different worlds somehow connects, and will the "Love Fireworks" come to life in time?
