My Brother Is Not Human

I have a secret. My mother is not my mother, my father is not my father, and my brother is not my brother. But we are a happy family, a happy family. Because my father who couldn't make me happy was raped by my brother, and my mother who couldn't make my family happy was raped by my brother. You ask brother? My brother is a god sent from heaven to save me. Huh? Mom, what did you say? Am I an only child? ... Brother, please don't change our family settings without my knowledge.
