Liu Changxue, the unfavored legitimate daughter of the Grand Tutor's estate, is ordered by imperial decree to marry Nangong Jue, the orphaned Prince of Zhenbei whom the outside world believes to be mentally disabled. On their wedding night, she unexpectedly discovers that all her inner thoughts can be heard by her husband, while she remains completely unaware of it. In reality, Nangong Jue is a forbearance-practicing God of War hiding his capabilities to evade imperial persecution. At first, he assumes Liu Changxue is a spy sent by the court, constantly testing and guarding against her. However, he continuously hears Liu Changxue's true innermost voice: she sympathizes with the plight of the General's estate, aches for his suffering, and is single-mindedly determined to revitalize the declining family business.
