An Ling is a well-known "undefeated queen" in the commercial litigation circle. She is very logical and sharp-tongued. He Siyue is a self-made technology upstart. He is decisive and aggressive in the market. He is recognized in the industry as a tough nut to crack. The two were sworn enemies in the court. Hess lost three times in the courtroom confrontation, and the more he lost, the more he got the better of him. He then focused on this cold-faced female lawyer. After a drunken accident, the two of them got the certificate in a daze and made a three-part agreement to start a secret marriage life. In court, the two of them were quarrelsome and refused to give in, and they were fierce rivals; in private, He Siyue turned into a protective maniac, blocking her from workplace difficulties and cleaning up bad relationships, and a bowl of hot soup could soothe the tough-talking Lawyer An. From tit-for-tat to fighting side by side, the two teamed up to raise capital, break through difficulties, clean up the chaos in the industry, and defeated their opponents step by step. Until the secret marriage was unexpectedly exposed, the whole industry was in shock: It turns out that the two most ruthless people in the industry are actually a couple? But no one knew that this unexpected marriage contained He Siyue's long-planned heartbeat.
