Su Nian is reborn back to her 19-year-old engagement banquet, cancels the engagement on the spot, and abruptly enters a flash marriage with the most influential veteran in the county. Relying on her advanced business vision, she sets up a stall and opens a shop in the 1980s, step by step growing her business. Facing entangling relatives and scheming rivals, she calmly responds and resolves them one by one, while the cold-faced military officer always stands firmly behind her, offering silent protection. A bond tied across two lifetimes brings both the thrill of building a career and the sweetness of a mutual sprint toward each other.
