In order to escape from the engagement, my eldest sister gave me the position of crown princess, and she happily married a "promising" dandy. She thought she had taken a huge advantage, but she didn't know that the man had changed his mind, was cold-blooded and ruthless, and only treated her as a pawn. I entered the East Palace, took care of the general affairs, assisted the prince, and established myself step by step. Five years later, my sister returned to Beijing in embarrassment and begged me for help. She asked me with red eyes why all the good things happened to you? I watched her decide your fate because of your choices.
