He Won't Save Me, So the Goddess Won't Return

In ancient times, a divine maiden spent her divine essence saving a young sovereign and fell into the mortal world. A hundred years later, she returns in her true form, only to discover that he mistook someone else for his beloved, and devoted the whole world to raising a fake stand-in. She is no longer angry and no longer explains herself. She watches coldly, waiting for Heaven's laws to collapse, so she can personally deliver his final judgment.
