Five years ago, the world-famous "Princess Zhuohua" Shen Zhuo died in a strange fire, leaving no trace of her body.
Her fiancé, Xiao Jin, the powerful regent, turned gray overnight and his temperament changed drastically. Soon, an orphan girl "A Shuang" who looked very similar to Shen Zhuo appeared next to him. She became his only comfort and was named "Mrs. Frost".
Five years later, a mysterious killer named "Jin Zhongshuang" emerged in the world. He was sure to fulfill any orders he received, and would only kill those who deserved to be killed for a huge price. She took on an unprecedented task: sneaking into the Regent's Palace and assassinating "Mrs. Frost".
When the sword edge of "Frost in the Ashes" pressed against the throat of "Mrs. Frost", deep in the eyes that were almost exactly the same as his own, he saw the familiar stubbornness and... Cry for help that belonged to "Shen Zhuo". At the same time, Xiao Jin, who was said to be crazy about his dead wife, was standing in the shadows, his eyes clear and sharp, and there was a cold and playful smile at the corner of his mouth that she had never seen before.
Who is she? Who is she? Who is he waiting for? A chess game in the name of love and hatred has been set. Who is the chess piece? Who is the chess player? When "White Moonlight" returns as a killer, when the "substitute" hides unknown secrets, and when the "madman" reveals his hidden fangs, the truth is more burning than death.
Concept: Identity is a prison, lust is a blade, on the chessboard of power and lies, only bone-burning pain can tell the truth
