In "Fog City", a bustling city where countless stories are unfolding every day, Lin Xiaoxing is a food delivery rider who shuttles through the streets. Her daily goal is simple and practical - deliver more food orders, collect enough money for her sister's medical treatment as soon as possible, and avoid that weird customer who always loves to "find trouble". Gu Yanshen is a top celebrity who stands at the top of the spotlight. He has tens of millions of fans and his every move is attracting attention. However, no one knows that this seemingly perfect idol has a serious "takeout dependence" and only looks for the same meals in the same store. In an accident, Lin Xiaoxing became Gu Yanshen's exclusive takeout delivery person. One was struggling for life at the bottom, and the other was shrouded in a halo in the clouds. The two people with different identities intersected over one takeout after another. From the initial misunderstandings and mutual dislike to the later understanding and silent protection of each other, they staged a funny and heart-warming love story amidst the fireworks and bright stars of the foggy city. During this period, they had to face the doubts of fans, the tracking of the media, the rules of the industry, and the tests of life. In the end, both of them found their true selves in this relationship, and let everyone understand that love has nothing to do with identity. As long as the hearts are together, all gaps can be overcome.
