Su Jin'er, a daughter born to a concubine, is an expert in the art of winning favor in the inner household. She originally hoped to marry into a princely household as a favored concubine, where she could enjoy an easy life, eat well, and do nothing until the end of her days. Unexpectedly, a twist of fate makes her the official wife of the heir apparent. She then teaches her husband, Shen Zhao, all her tricks: playing the victim, winning sympathy, and shifting blame onto others by using their influence. Little does she expect this seemingly gentle but secretly cunning heir to take the tricks of the inner household into the imperial court, where he wins over the Crown Prince, secures the Emperor's favor, and toys with the entire court of officials, rising all the way to the throne. Both are devoted and powerful in their own right. Married before falling in love, they share a sweet romance filled with mutual affection. Watch as a concubine-born daughter turns an ordinary man into an emperor!
