Natsuha Shinomiya

Natsuha Shinomiya is Yuu's childhood friend and lover. She's a year older than him. They live in a remote village so they take about 40 minutes to go to school by bus. Their family both live close to each other so they've known each other since they were kids but Yuu lost contact with her for a year after she graduated from middle school, one year before he did, but he applied to the same high school she goes to in order to be with her again. He confessed to her after starting high school and that's how they became lovers.
