My older brother, who loved 'Mayu' since he was little, returns to his hometown after several years. However, he shocks us with the revelation that he came to tell our father about his marriage. If I can stay connected with my brother as he drifts away, I'd give up everything precious to Mayu. A forbidden and sweet yet sorrowful ending awaits Mayu and her brother in their sexual act. ...Goodbye, my only big brother.
