Mom, I’ve Transmigrated

I transmigrated to another world. Why did I end up here? Of course, I had to find the truth... As a soul from another world, I was lucky enough to be loved by my senior brother, the Demon Lord, the Young Lord, and the Palace Master. I had no idea I was so charming. What! I was once the Celestial Maiden? The Immortal Realm is my home? And I’m burdened with a deep-seated vendetta? Is the Demon Lord my enemy?
