Duan Fei is a Special Forces agent who marries Yun Shi Tong, yet their marriage is only a cover to better protect Shi Tong from the assassination attempts against her life.

The female president Yun Shitong ( played by Zhao Yuxi ) and the special force agent Duan Fei ( played by Han Zhishuo ) have not seen each other for many years. When they meet again, they have to get a "marriage certificate". However, Yun Shitong does not know that this is for the convenience of Duan Fei. Protecting himself is also the task that Duan Fei, a special soldier, has received. The married life of the two then starts stumbling, and the couple is in dilemma about their relationship. The series of setbacks and dangers Yun Shitong encountered in the shopping mall were all overcome with the help of Duan Fei and his brothers. At the same time, the relationship between the two also heated up sharply. The couple who got married out of desperation "did a fake show and really did it" and germinated to become true love.
