Ichika lives on a remote island in Nagasaki Prefecture and has long been in love with her paternal uncle. Though he works in the city and rarely returns home for extended periods, Ichika doesn't mind—she thinks of him every day. One day, she learns that a concert by her favorite singer will be held in the city where her uncle lives. She tells her parents only, "I want to go to the concert and stay at my uncle's house," and decides to travel to the city alone. For Ichika, who has felt the distance of their separation deeply, this trip marks a special first step.
