When frontier general Lin Shuangyue rescued the taciturn "Young Master Shen" from a merchant caravan, she never expected that she had brought home a blazing sun. Censor Shen Zhao had entered the frontier with a secret imperial decree, intending only to uncover the truth about her elder brother's final battle. Instead, she encountered the only moonlight of her life: Lin Shuangyue, her silver armor stained with blood but her back held straight, just like the ideal Shen Zhao had never dared to voice.
They were the two sharp edges of the same sword. They confided in each other beneath the moon and played chess in the tent. Every meeting of their eyes was a wordless understanding. Then Shen Zhao took an arrow meant for her, and Shuangyue cried her name before thousands of soldiers. All the feelings they had restrained, all the passions surging beneath the surface, could no longer be hidden in the face of death. They blazed across the wilderness like wildfire.
The hand of conspiracy closed around the capital and the frontier at once. One used her wits to break the deadlock, standing alone to move the pieces at court. The other defended the city with her blood, turning the tide amid a rain of arrows. Apart, they were two separate flames. Together, they were a light that could burn away the darkness.
In the end, they chose a third path. They would not return to the capital, nor confine themselves to defending the frontier. They would share command and establish new laws, building a new world of their own, where the sun and moon shone together, on the frontier that had buried countless loyal soldiers.
Once two souls recognize their reflections in each other, they can no longer be parted. What they sought to protect was never the border, but the clear and untainted land in each other's eyes.
