In the previous life, Shi Anxia, the daughter of a general, was framed by her concubine and her fiancé. The family was destroyed and she died unjustly. When she was reborn on her wedding day, she decisively abandoned her betrayer and chose Xiao Jin, a playboy in the eyes of the world, as her husband. Faced with everyone's ridicule, she made a one-year peace agreement with Xiao Jin. However, this apparently bohemian "Devil King" secretly helps her get revenge: he eliminates her old enemies, prepares military supplies for her, and clears obstacles for her in the court. When power and sincerity are put in front of her at the same time, Shi Anxia must make a choice between revenge and rebirth. Xiao Jin's true identity and purpose will also completely change her understanding of this marriage.
