Everyone said that Shen Zhitang was able to marry into a high-ranking family because of his face that looked so much like Gu Huaizheng's late wife.
She is a perfect substitute, a docile puppet, and a "new flower" beside the "old sword" in his heart to remember his old dreams.
Gu Huaizheng thought that she only needed to live quietly as a shadow.
Little did he know that she had a pair of eyes that could penetrate people's hearts. She could hear the murderous intention in his pause, see through the betrayal in the maid's eyes, and accurately grasp the only way to survive from the laughter of the guests in the hall.
At first, he married her to forget.
Later, he kept her because of fear - fear that without her, no one in the world could understand him so thoroughly, including himself.
When the "shadow" starts playing chess, the "substitute" becomes the guest.
In this game in the name of love and memory, who is helping whom, and who is taming whom?
