In the Fog City, which is shrouded in thick fog all year round, Lin Xia, a 25-year-old Internet social worker, lives a life of "working overtime until late at night, taking out food and being lonely". His only wish is to save enough money to escape from the "Capital of Volume Kings". Until one rainy night, she picked up a mysterious man named Ah Xing, who was covered in wounds and could emit light blue fluorescence next to the trash can in the community. Her peaceful life was completely disrupted. Ah Xing claims to be a stranded stranger from the "Stardust Galaxy". After the spacecraft crashed and the energy was exhausted, not only can his fingertips produce fluorescent light, but his six hidden silver-blue arms and legs can also spawn plants and repair small objects. Lin Xia originally wanted to "keep her in for a few days and make ends meet," but she gradually became dependent on this "alien fool" after Ah Xing used fluorescent arms and legs to cook "Yangchun noodles with stars", helped her get a PPT that amazed the leaders, and even rescued stray cats in the community when they were in danger. But as "luminous plant injury cases" appeared one after another in Fog City, and the mysterious research institute frantically hunted down A Xing, Lin Xia discovered that A Xing's arrival was no accident. Behind the thick fog that persists all year round in Fog City, there are huge secrets about alien civilizations hidden. While trying to cover up Ah Xing's identity and evade pursuit, the two of them searched for the energy core to repair the spaceship. In the foggy city, they embarked on a warm and exciting cross-planet co-renting adventure.
