The heroine Su Muqing, as the illegitimate daughter of the Su family, has endured her anger since she was a child, just to exchange for her mother's peace. She was used as a marriage tool and betrothed to Lin Yufan, the heir to the Lin Group. However, at the engagement party, her half-sister Su Ruoxue and Lin Yufan teamed up to frame her for misbehavior, which resulted in her being kicked out of the house by her furious father and leaving her with nothing. Her mother was so angry that she was seriously ill and hospitalized.
Five years later, Su Muqing returned as the top lawyer "Mu", calm, rational and invincible. The first case she took over put a well-known company into dire straits, and the backer of this company was none other than Lin Yufan. From then on, she worked step by step and used the law as a weapon to bring down those who had bullied her one by one. In the process, she unexpectedly met Fu Yeshen, the most mysterious and low-key business emperor in Beijing. Fu Yeshen was attracted by her fragility and tenacity under her calm and powerful appearance. From the initial appreciation to the deep fall, he became her most solid backing on the road to revenge. Under the protection of Fu Yeshen, Su Muqing not only completed the ultimate revenge against the Su family and the Lin family, uncovered the truth about her mother's murder, but also healed her inner trauma. In the end, she gained both career and love, and became a real queen.
