[Both leads are faithful to each other + rekindled love + she chases him after the breakup + daily life + quirky young lady x cold-faced prince] When Wen Yan opened her eyes, she discovered that she was married. Her husband was none other than the Fourth Prince, Pei Yixing, famous throughout the capital and beyond.

With things as they were, Wen Yan could only turn to The Art of War: the self-injury ruse, feinting east to attack west, hiding the truth in plain sight... She tried all thirty-six stratagems.

Everyone thought Pei Yixing had long since given up. In reality, every night he studied the words and actions of Wen Yan's lover. He was sure Wen Yan would come back sooner or later.
