I am a noble daughter of a noble family and the concubine of King Yan Ji Songan. He bullied me and humiliated me, trampled me in the mud but said he loved me. No one knows that I am the eldest princess's internal agent, and I am here just to help her ascend to the throne. I found the previous spy. She was blinded by love and was willing to be killed by Ji Songan. Before she died, she informed me of the existence of the secret decree. I was punished for this and was forced to kneel down and bark like a dog in front of my relatives, friends and the eldest princess. Later, I sacrificed myself to detoxify Ji Song'an. After gaining trust, I helped the princess find the secret purpose, caught the fleeing Ji Song'an, and eliminated future troubles. I assisted the eldest princess and carved a path for women in the world to become successful.
