A calculated hidden marriage pushed Su Wantang into the center of a wealthy family's storm. She is a cold beauty who is cold on the outside and ruthless on the inside. She is restrained on the outside but sharp in her bones. Others use marriage as a bargaining chip, but she uses evidence as a knife; others force her to take sides, but she insists on overturning the table and rearranging the rules. Hot searches, backstabbing, beard cutting, and backbiting are taking place one after another. Pursuit and temptation coexist, and desire and power intersect in the night. Gu Chenzhou thought he was protecting her, but later he discovered that she had always been the one who really controlled the situation. She doesn't rely on tears to get to the top, she only relies on her brains and wrists to defeat the audience.
