Lin Wanxing failed in his 12th blind date and complained to his best friend, "If you push me to get married, I'll get someone married." This happened to be heard by his immediate boss, Lu Chengze, who was forced to marry by his grandfather. The next second, Lu Chengze handed over the "flash marriage agreement": "Everyone gets what they want, and we will divorce you in one year. I will pay you 100,000 yuan." The two of them obtained the certificate at the speed of light, and had to abide by the company's "no office romance" regulations, and started a life of secret marriage.
At work, he was a serious director, and she was a well-behaved subordinate, who had to pretend not to know each other even when handing over documents; after get off work, the two of them lived in the same room and slept in separate rooms, but things always failed due to "accidents" - he helped her wipe the corners of her mouth with cream, and she helped him cook stomach porridge. What's even more troublesome is that the new designer Chen Yang is pursuing Lin Wanxing, and his partner Suman is keeping an eye on Lu Chengze. The jealous two people gradually become sincere in their "acting".
From grabbing snacks in the supermarket and being misunderstood by neighbors, to pretending to be relatives at the annual party and overturning the relationship, there are more and more flaws in hidden marriages. Finally, at the project celebration banquet, Lu Chengze took Lin Wanxing and announced in public: "She is my wife, not a colleague." This flash marriage, which started as a rush to get married, eventually became a true love that goes both ways.
