She "died" on the execution ground on a snowy night, cut to pieces with no bones left - only she knew that was her first move.
After six years of being raped and executed, she changed her identity and returned to the palace, investigating old cases and guarding against new ones. Her childhood sweetheart's fiancé has become a backstage for her rival's family, her uncle-like father-in-law is the culprit of her family's harm, and the sisters who once wanted to be friends are now standing on the opposite side of the knife.
She won this game, but the game was never really finished.
Purpose: To explore how, in the struggle for power, living soberly and seeking justice for the deceased requires more courage than blind revenge; at the same time, it shows how everyone in the chess game (including the villain) is pushed step by step by the involuntary situation to an ending that they may not want to.
