"Substitute marriage? Living King of Hell? I, Su Wanyue, must bloom in this hell!" An imperial edict pushed Su Wanyue from the backyard of the Su family into the Regent's Palace, becoming the substitute princess for the notorious and powerful Xiao Jue. She melted the ice in Xiao Jue's heart with her optimism and sincerity. From initial indifference, to unconscious protection, and then to desperation at the critical moment of life and death. (Xiao Jue: Why does this woman always make me feel uneasy?) She used warmth and patience to make Li Xuan go from "useless person" to "indispensable". From harsh ridicule, to secret help, to heartfelt following. (Li Xuan: Strangely, her tea seems... Not so hard to swallow.) She used care and understanding to make everyone in the palace go from being wary and distant to being intimate. From turning a blind eye, to taking the initiative to protect her, to being willing to go through fire and water for her. (Zhang Hu: The princess said that we are not wild beasts, but her family!) Inside and outside the palace, with a warm heart, she turned the villain Tiantuan into her exclusive "White Moonlight Guardian". However, when she unintentionally uncovered the tip of the iceberg of the power struggle in the capital, she discovered that her identity as "White Moonlight" actually made her the key to the imperial power chess game! "No, I just want to live a good life, why have I become everyone's weakness and target?!"
