Yun Zhiyi is intelligent and transparent, has read poetry and books since childhood, and has the character and calmness of a scholar; Chu Yi is a loyal, brave and courageous young general who guards the border all year round. He has a cold temper and is not good at words. The two had had many conflicts since childhood and were known as "rivals" in Beijing. However, because the emperor wanted to stabilize the court through civil and military marriage, they were tightly tied together by an imperial edict granting marriage.
At the beginning of their wedding, the two made a "three-part agreement", agreeing not to interfere with each other, to act as a loving couple, and to get together and separate when the time is right. However, as they get along day after day, from the unexpected protection at the palace banquet to the tacit understanding of the Linglong Pavilion; from Chu Yi's carefully prepared betrothal gift and the courtyard layout that suits his heart, to Yun Zhiyi's sole support of the Chu mansion after he leaves the capital, calmly dealing with difficulties from all sides, the nominal couple, through repeated trials and confrontations, gradually get a glimpse of each other's delicacy and responsibility under the cold appearance.
The beacon fire at the border was ignited, Chu Yi rushed to the battlefield, undercurrents surged in the capital, Prince Rui and Princess Jianing repeatedly provoked each other, Yun Zhiyi stuck to the Chu Mansion with a weak body, guarding their "territory"; while Chu Yi, who was far away at the border, also felt unspeakable concern for the calm and tenacious figure at home during the war.
When political games, past grievances and quietly growing feelings are intertwined, can this couple, who started out as "acting", break their original agreement and truly understand the deep meaning in each other's eyes amidst the ups and downs?
