In Iwaki City, Fukushima Prefecture, two fifteen-year-old students—Hikaru and Saki—are in love. But after the nuclear accident, Hikaru’s family evacuated to Niigata, so that the couple was separated. Thirteen years later, now 28, they live their own lives in Tokyo and Iwaki. They reunite at the photo studio of Hikaru’s father. Though they still care for each other, Hikaru, who left his hometown, and Saki, who decided to stay there, struggle to connect. Hikaru is tormented by the irretrievable loss of 13 years. But when he discovers a photograph, he comes to understand why his father fought so hard to keep the studio running and confronts his regrets. Now, as an illustrator in Tokyo, Hikaru begins to heal Saki’s heart by drawing the “shutter chance”—the happiness she missed photographing during the past 13 years. He then renovates his father’s old studio into an atelier, aiming for the revitalization of Iwaki. There, the photos they missed are displayed. What path will they choose from here?
