At the wedding venue, a four-year-old adorable tot suddenly drops in and shouts "Daddy", causing the contract marriage to crash on the spot. Known as the "walking bomb disposal expert", risk control queen Jiang Xintang smoothly takes over, transforming from a business partner who calculates clear accounts with business president Shen Shi into comrades dismantling traps side by side.

From a single piece of agreement to a house full of fireworks, with a double blessing arriving at the door for a perfect conclusion, this is a highly sweet and satisfying urban healing family comedy-drama.
