Shen Zhao, the revered chairwoman of a conglomerate, was accustomed to absolute control. No one knew her true desire: for someone else to make her decisions. An anonymous encounter led her to unexpectedly kneel before Cheng Lu, her assistant of seven years. By day, Cheng Lu respectfully addressed her as "Ms. Shen"; behind closed doors, the collar, the keys, and her activities for the night were all in Cheng Lu's hands. Later, Shen Zhao met Tang Ning, an intern. Younger than her, Tang Ning was the one who truly dared to catch her. From private training to a secluded academy; from "Ms. Shen" to the designation N17, and then to the little bitch on a leash by the Master's side. She thought she merely wanted to temporarily relinquish power, but step by step, she was drawn into a hidden world connecting wealth, desire, and the highest echelons of power. And she finally discovered that harder than kneeling was, after truly surrendering herself, still having the courage to be Ms. Shen again.
