With a marriage proposal, I became the crippled king's substitute princess. On her wedding night, she was framed and charged with stealing someone. My husband wants to be killed, the Queen Mother wants to be humiliated, and I am even more of a chess piece placed by the Third Prince in Prince Chen's Mansion. In this interlocking puzzle, only by using myself as bait can I escape unscathed and find a way out of my own way.
