Lily Potter looked at her sleeping daughter in her arms and became even more determined to work with her husband and friends to eliminate the Death Eaters and Voldemort and create a better future for her children. Unfortunately for the shrinking British wizarding community, only one boy was born into a pure-blood family on the day Harry Potter was born. We all know the subsequent story, including Trelawney's prophecy and Snape's betrayal, but what no one expected was that Voldemort stubbornly believed that the wizards would change the child's gender repeatedly in order to protect the chosen one. It wasn't until his death curse was deflected by the little baby girl that he reluctantly discovered that he might have been wrong from the beginning.
If the self-willed Voldemort identifies a baby, what awaits him is not only the hardship after rebirth, but also the betrayal of everyone.
Concept: Illusive love can actually defeat the devil in the end.
