Marshal Gu Qingyan was assassinated by a political enemy and died in a theater with pistils flying in the arms of Shen Zhinian, the love of his life. The blood dyed the silk handkerchief in her hand embroidered with the word "Qing Yan" red. In the great grief, Shen Zhinian's consciousness was blurred. In a trance, a voice echoed in her mind:
"Do you want him to live?"
"With your existence, the other person's life will be changed. Once the contract is completed, you will be erased from this world, like a mirror, a flower in the water, and no trace."
"I do." - This was her only answer.
