Tsubame lives in a warm environment with her father Toshio and stepmother Asako, but, one day, she learns that Asako is pregnant. She feels left out because of her stepmother’s pregnancy and she also feels frustrated because she can’t reveal her love to Toru. The rooftop of her calligraphy class is the only place where Tsubame can find solace. There, she feels the wind and looks up at the stars.
