The Broken-Fingered Secret Guard of Princess Yaoguang on Jinshang

In the seventeenth year of Zhanghe, Chu Yao was taken back to the imperial city from Ganye Temple and became the most inconspicuous abandoned princess in the palace. Carrying the grievances of her biological mother and the secret skills of making incense, she worked every step of the way, but she didn't know that a shadow was always following behind her. Shen Jin, codenamed "Crow", is a monitor placed by the Queen Mother beside her. The severed finger on her left hand hides an unknown past. He was ordered to record her every move, but as they got along day after day, he was moved by her tenacity hidden under her meekness and her gentleness hidden behind her guard. He is a shadow, who should be ruthless and loveless, but he makes exceptions and breaks the rules for her; she is an abandoned daughter, who should not trust anyone, but gradually becomes dependent on this silent handyman. There is an undercurrent of intrigue in the palace, and the battle for the throne engulfs the two of them. When the task of "surveillance" conflicts with the instinct of "heartbeat", and when her grievances are intertwined with his past, can they break free from the shackles of fate - using the body of shadow to protect Yaoguang's safety; with the rest of their lives as a promise, they can cross each other out of the abyss?
