Adam and Barra are half-siblings who are separated. Their parents were worried that Adam would do indecent things to his younger brother who was an omega. Several years passed, Adam was 18 years old and Barra was 16 years old. Barra attends the same high school as her older brother. They both do not know that they are brother and sister. At the school where they are in there are rules that alpha and omega are put together to complement each other. Adam and Barra apparently share the same room!!?
