She was a concubine, and she accepted her fate; she was used as a pawn by her father, and she accepted her fate; she was forced to marry the ailing prince as his stepmother, and she accepted her fate; it didn't matter if they all lied to her, so why did he lie to her too.
The political enemies were eliminated, the city was captured, and the imperial city was captured. She did everything she had to do. She didn't even mind the potion he rewarded him on their wedding night, nor did she mind the green clothes and red clothes around him. She even helped him usurp the throne. In the end... He sent her to someone else's bed...
Since you lied to her, why can't you lie to her for the rest of your life? Why should you give up halfway...
