On the wedding night, the husband entered the house with his concubine and forced her to commit suicide with a letter of divorce. The whole capital was waiting to see the joke of the stupid concubine in the prime minister's palace. Unexpectedly, her eyes flashed, she tore up the divorce letter and exposed the shocking conspiracy in public. Her fiancé, who used to think she was stupid, knelt down and begged for mercy. Her stepmother and concubine, who bullied her and humiliated her, were ruined. No one knew that the powerful, ruthless and murderous regent would protect her behind him and ask in a mute voice with red eyes: "Hong'er, where else can you go besides me?" She was the reborn avenger and the only white moonlight he kept in his heart.
