In a seemingly prosperous and peaceful corner of the capital, the pretty sweet water shop proprietress Tang Tang has captured the discerning taste buds with her fascinating and exquisite desserts. Shen Zhiwei, the chief minister of the court and the cool imperial doctor, has become her guest. However, the hawk-like gaze of Lu Feng, the commander-in-chief of Jinyiwei, was always fixed on the "golden osmanthus flowers" in her backyard. Beneath the sweet frosting lies a deadly blade. On a rainy night, the Xiuchundao pierced the tranquility, and the accusations from the remnants of the previous dynasty exploded like thunder. The lancet that slipped from Tang Tang's sleeve and the blade that Lu Feng took away from her hand cut open the veil of her dual identity.

Frost and knife are intertwined, sweetness and murderous intent coexist. Can she keep her "recipe" and sincerity amidst the overturning fate?
