Liu Qinghe, an abandoned concubine in the cold palace, appears to be a gentle and well-behaved little white rabbit, but in fact she is well versed in poison and has a sinister heart. She originally just wanted to raise a cat and lie down in the cold palace, but unexpectedly, the current regent Pei Yanzhi (rumored to be violent and bloodthirsty, but in fact he was feared by the society as an arrogant and petite young man) was given to her as a "temporary husband" by the late emperor's decree.
One was forced to lower his dimension to fight against the scumbags in the palace, and the other was forcibly dragged out of the cold palace to "do business". Qing He used his killing skills to teach the prince how to fall in love, and the prince used more than ten thousand people to support Qing He. While the civil and military officials in the court were waiting to see the joke, this anti-cute couple kept pushing and amusing the powerful people - until Qing He discovered that the birthmark on the prince's waist was exactly the same as the figure that appeared repeatedly in her dreams.
