From Palace Maid to Empress

An ordinary-looking palace maid suddenly went from sparrow to phoenix, becoming the emperor's concubine. She thought it was heaven's favor, but it turned out there was more to it. She had hoped to keep her head down and stay out of trouble, but kept being framed. So she had no choice but to fight her way through every obstacle and carve out a place to survive beneath the red walls and golden tiles. (In short, it's the story of a palace maid who was used as a substitute and rises all the way to become empress.)

P.S. If it's not for you, please move along. No hate.
