In the glamorous but turbulent modern urban business world, Lin Zhi, a rational, pragmatic and highly capable strategic consultant, signed a "hidden marriage agreement" with her husband Lu Tingshen from a flash marriage for the sake of her career. She just wanted to be promoted based on her strength, but unexpectedly on her first day of employment, she met the new CEO who was her bedfellow. Lu Tingshen appeared to be cold and difficult, but in fact he set up a trap every step of the way just to force her to take off her guard; the two of them in the company pretended to be strangers, but after returning home, they closed the door to settle the "accounts". When Vice President Jiang Che steals her core plan and childhood sweetheart Xu Ruoyun uses the opportunity to disrupt the situation, Lu Tingshen does not hesitate to confront the board of directors to protect her. This marriage, which began as a contract, quietly deteriorated amidst crises and side-by-sides - he could no longer tolerate it, and she could not escape it. The chess game of marriage first and then love finally goes in both directions, and reason and possessiveness collide to create the hottest spark of love.
