On the day the Prime Minister married Qingmei, his first wife Shen Qingshuang faked her death and fled to the south of the Yangtze River. Unexpectedly, the prime minister discovered the empty coffin and was furious, pursuing him with all his strength. During her escape, Shen Qingshuang met the mysterious scholar Xiao Yunzhi and the Western Region businessman Ashina, and gradually uncovered the shocking conspiracy behind the arranged marriage three years ago - the Queen Mother's hand, the Emperor's suspicion, and the Prime Minister's forbearance. When the truth came to light, she discovered that the man who had neglected her for three years actually used the most clumsy way to protect her.
