The Happy Little Lady of the Duke's Mansion

An ordinary peasant girl was sold into the government by her cruel aunt. Congratulations to the Duke and the Crown Prince. I thought I would be buried with the prince, but unexpectedly, I became a blessing in disguise and became the lucky star of the house. But she was just a little concubine, she had no family background, she couldn't sing or dance well, she couldn't do anything, she was just mediocre. Seeing the people in the house coming and going, the flash of swords and the shadow of swords, I just want to say, don't come here~
