"After sunset, you are me and I am you." This strange curse tightly entangles two completely different lives.
Shen Yan, the youngest Minister of Punishment in the Zhou Dynasty, was known as the "Iron-faced Judge" and was known for his coldness and harshness. Su Zhi, the folk embroiderer, is gentle and quiet, but every night she turns into the man who scares the government and the public. And every morning when she wakes up, Shen Yan will find herself lying in the boudoir of the embroidery workshop, with the touch of embroidery thread still left on her fingertips.
This absurd soul exchange originated from a bizarre murder case. The incomplete "Thousand Silk Embroidery" on the deceased's body was the lost skill of the Su Zhi family. When Shen Yan pressed closer and closer in the court, and Su Zhi peeled off the cocoon in the market, they gradually discovered that the murder case ten years ago and the murder case today all pointed to the same shocking truth.
During the day, he was a cold-faced minister, and she was a weak embroiderer; at night, she was in charge of the prison for him, and he was flying needles and threads for her. In this identity puzzle, the most dangerous thing is - when the sun sets, who will be tempted first?
