Ming Yuan is a symbol of evil that brings pain to those around him even if he doesn't have the slightest malice in his heart. In another world, "Plague City", Ming Yu, as an immortal, almost massacred the city because he "thought everyone was in the same pain as himself, so he wanted to help them get rid of their pain." After the misunderstanding was solved, she felt guilty for what she had done, so she took the initiative to be punished by the protagonist. Finally, after losing her memory and being reincarnated into this world, she became an "angel" through brainwashing.
