In order to save his seriously ill father, Su Heng, an ace lawyer at a top law firm, signed a hidden marriage agreement with Gu Yan, the president of the business giant Gu Group. The two started from a contractual marriage where each got what they needed, and gradually became attracted to each other's professional abilities and sincerity when Su Heng was dealing with the Gu family's legal crisis (family inheritance dispute case, transnational commercial espionage case, industry monopoly litigation). Su Heng relied on his legal prowess of "arguing like a sword in court and peeling off cocoons like a spider in court", breaking out from the label of "Mrs. Gu" and becoming the "god of war lawyer" in the industry; while Gu Yan completely shed the disguise of "business machine" in the process of witnessing Su Heng's career highlights. In the dual battlefield of career and emotion, the two completed the two-way redemption from "contract couple" to "soul mates". The full text takes "hard-core legal confrontation + hidden marriage and sugar knife interweaving" as the core, emphasizing workplace pleasure and emotional tension in parallel.
