Shen Wanwan, the daughter of the guilty minister, hid in the courtyard of the Hou Mansion, using a paintbrush as a cover to secretly investigate the truth behind her father's injustice. The border food draft three years ago was like a tight net, trapping the gentle smiles of the Gu family, the weirdness of the Zhou family, and the fate of her and the cold-faced Marquis Xie Jingci.
The painting book handed over by Gu Yunzhou contains secret words, and the old account book in Xie Jingci's sleeve contains secrets. When the calculation under the mask of warmth gradually becomes apparent, and when the protection under the frost shell becomes clearer, a magnolia hairpin and half an agarwood plaque lead her to test the gap between conspiracy and sincerity step by step.
She thought she was investigating her father's unjust case, but she didn't know that she had already stepped into a puzzle involving grievances, temptations and affection - and the person who always protected her in the dark hid a secret that was heavier than the truth.
