In "Fog City", a city that is half steel forest and half retro alleys, Lin Xiaoman and Shen Zhixing are well-known "rivals" in the circle - one is a "conspicuous bag" in the dessert industry who runs an Internet celebrity dessert shop and is chased by customers for recipes every day, and the other is the "President of the Dessert Industry" who runs a technology company and can train his subordinates to doubt life in meetings. The only intersection between the two is that they grab a window seat at the same cafe every Wednesday afternoon. But who would have thought that after a sudden thunderstorm, the enemies would actually exchange memories! Lin Xiaoman woke up and found that his mind was filled with "KPI assessment" and "code optimization", and he had to explain "business logic" that he did not understand to a group of people in suits and ties; Shen Zhixing, who was filled with "cream whipping skills" and "fruit plate aesthetics", was forced to recommend to customers "Today's tiramisu is just right, like the feeling of first love." What's even more outrageous is that they have to pretend that there is nothing wrong with them, and they are busy dealing with each other's lives while looking for ways to change back. In the process, they gradually discovered that behind the original "rivals" there was a softness they had never seen before - Lin Xiaoman seemed heartless, but in fact he was silently taking care of his sick grandma; Shen Zhixing seemed cold and mean, but in fact he was secretly funding technology classrooms in remote areas. When the fog of memory gradually lifts, will this pair of "forced-bound" enemies change from "ruining each other" to "running in both directions"?
