The war ended. In an accident, the scarred Harry Potter traveled to the fifteenth year after the end of the war, and his soul actually settled in the body of a newborn baby. He was horrified to discover that the father who raised him was Draco Malfoy, his former rival, and Draco was gay. There were traces of the existence of another owner everywhere in the house, but he was never seen. As he grew up, Harry gradually uncovered the cruel and affectionate truth among countless old objects, memories and words from others - Draco's deceased husband was his future self, and this love that transcended grudges was a destiny that was completely unknown to him at this time. From Harry's perspective, the book unfolds a story about Deha's sadomasochism that spans time and space, entangles life and death, and is full of regret and affection. It is a million words long and delicately depicts the entanglement of love and hate, identity struggle, and fateful affection under the dislocation of time and space.
