Zhao Leyao, the most favored princess of the Dayin Dynasty, met Shen Yuan, the chamberlain who had purified herself and entered the palace. He is the most inconspicuous servant in the Yeting Bureau, but he has a pair of eyes that can reflect the stars. He picked up the hosta she accidentally left behind in the shadow of the palace wall. The barrier of identity was supposed to be an eternal separation, but because of her stubbornness and his forbearance, a forbidden love grew up in the heart-wrenching palace. Without telling the Holy Master, she stuffed the heater into his frozen palm, and he risked his life to steal folk sugar paintings for her; she broke the golden bottle when she refused to marry him at the talent show banquet, and he protected her in the dark night and spattered blood in the corridor. When the emperor noticed the clues and sent Shen Yuan to prison for "disgraceful palace", Le Yao knelt in the Jinluan Palace wearing a wedding dress and offered him half a life in exchange for the princess's seal. However, before Shen Yuan was executed, someone sent him a broken hairpin, which was engraved with the peach blossoms she had drawn casually when she was young - it turned out that he was once an orphan of a general, and invited himself to the palace for revenge, but the moment he met her, his blood feud turned into a finger-wounding wound. In the end, he died under the torture of the palace, and she was trapped in the palace of the bride. Separated by thousands of palace walls, only the broken hairpin glowed coldly in the moonlight, reflecting a desperate love that was crushed by the imperial power and made her hold her breath even when she cried.
