A Tale Lost Before the Common Era

Twenty-five years ago, she wiped out his entire clan and stood high above him. His heart was filled with hatred, and he lived only for revenge. Twenty-five years later, she had vanished without a trace, her fate unknown. He ruled the world, his imperial heart hidden behind nine layers of walls. Twenty-five years ago, she searched for him. Twenty-five years later, he searched for her. Was it hatred? Was it love? She had loved before, while he had a harem of three thousand. And the sudden appearance of a demon prince made their already tangled, confusing relationship even more complicated. (This is my first time posting. I hope you’ll all show me lots of support :)) Theme:
