In his previous life, the protagonist was a concubine of a prince's family. He was innocent and kind-hearted, but was betrayed by the family's legitimate son, stepmother, and powerful court officials. Not only did he lose his beloved, he was framed to death, and his family was destroyed. After rebirth, the protagonist carries the memories of his past life and uses his golden finger to know the secrets of all parties, and becomes scheming and selfish. He faces many obstacles from the palace and family forces, who will do anything to suppress the protagonist in order to maintain their power. If the hostile forces cannot be brought down before the situation in the palace completely deteriorates, the protagonist will lose everything again, and the family will never be able to turn around. In the process, the protagonist finds it difficult to trust others due to trauma in his past life, and is forced to deal with betrayers from his past life. Although he succeeded in revenge, he discovered that part of the truth was not as simple as it seemed, and he had mixed emotions in his heart. But he continued to grow in the predicament, taking advantage of the contradictions between all parties, gradually accumulating strength, and finally broke fate and reversed the situation.
