Everyone says Song Shuangning is a gentle and innocent girl, with timid eyes and a slender figure. But no one knows that beneath this delicate exterior lies a cunning and ruthless woman who schemes and plots against concubines, and is adept at using witty and sarcastic remarks.
Xiao Yan had seen all sorts of women, but he was particularly captivated by this "innocent little flower" at first sight.
She is gentle and kind, like the bright moon; she is considerate and sensible, like the warm spring sun; she is understanding and knows him in everything, a true confidante rarely found in this world.
But gradually, he discovered that this little white flower was repeatedly revealing its flaws and its unknown "badness," and Xiao Yan found himself liking it even more.

Xiao Yan: "What's wrong with my imperial concubine doing something naughty?"
