When she was eleven years old, she regarded her as her very good sister who died protecting her stupid sister. Her mother called her "Si Yun". From then on, she was her sister in front of her mother.
At the age of twenty-one, her "employer" ordered her to change her name. It was said that she looked very much like his missing sister. Her work partner, an elderly couple who could not stand the stimulation, called her "Tingting". From then on, she was a stranger in front of him.
At the age of twenty-two, he hugged her body and kissed her, calling her "Jingyun". At that moment, she was his first love in front of him, his dead brother's wife.
Is she Cheng Siyun? Is she Yin Zhaoting? Is she Jiang Jingyun?
She, Cheng Zetong, is destined to be a substitute in this life!
