Li Xia, an art designer of a game company, entered a newly-developed game as a closed beta player coincidentally and became an ugly maid who does the cleaning in the palace. She started a love-hate relationship with the "cat-like" Emperor Yang Mo in ancient times and her fortune began to change for the better. As the two are more and more devoted to each other, they get to know that the only way to quit the game is for him to die.
