During the Yongxi period of the Great Chu Dynasty, undercurrents surged in the court, and the struggle between aristocratic families and poor families enveloped countless innocent souls. Lin Lan, an orphan from the general family, was wronged by the Xue family. She disguised herself as a man and entered the official career under the pseudonym "Lin Yu". She used resourcefulness as a blade to navigate the treacherous officialdom step by step.
She first showed her talents in the imperial examination, and also got a glimpse of the blood behind power while serving in a dangerous place. And Su Yichen, the son of a bachelor of the Hanlin Academy, is like the moonlight in the dark night, warm and transparent but with a deep heart. He admired Lin Yu's determination and sincerity. The two of them went from cherishing each other when they met by chance to caring for each other when they were in danger together. They supported each other in the whirlpool of power and intrigue, and they unknowingly touched the heartstrings.
As Lin Lan gradually gets closer to the truth about her family's injustice, and discovers that the man behind the scenes is targeting the powerful Prime Minister Zhou Chong and his members, she and Su Yichen are involved in a deeper chess game - the undercurrent of the prince's struggle for the throne, the suspicion of the border war, and the intertwined forces of the aristocratic family, tightly bind the fate of the two. They must not only balance the forces of all parties in the court game and expose Zhou Chong's conspiracies, but also stick to their original aspirations amidst the confusion of identity and the pull of emotion.
The road to green clouds is far away, and old dreams are hard to find. Can Lin Lan find a way back between revenge and morality? Is Su Yichen's "white moonlight" a beacon for her to move forward, or is it a fetter set by fate? When the truth is revealed and power is shuffled, can they finally work together to clear the fog, restore clarity to the world, and realize their dreams?
