In the future interstellar era, those with awakened spiritual powers conquered each other. After the war, the loser Lu Beichen was labeled a "crazy beast" and was exiled to a marginal mental rehabilitation center. The new psychotherapist Gu Yun, on the surface, is a gentle and harmless first-level hypnotist in the galaxy. In fact, he has an ability that only he knows - he can see the afterimages of the past life memories of every person who has a mental breakdown. In Lu Beichen's previous life, he was a demon king who slaughtered all the people in heaven in order to resurrect him. In this life, he will personally cure the crazy Demon Lord bit by bit into the person who loves him.
