This is a vigorous friendship story and an unforgettable love story.
Zhou Ye, Gu Chu, Jiang Huai, An Xi, Chen Mo, and Qi Yu are childhood sweethearts who grew up together.
The parents of the five were colleagues in the police station. Because they were often busy with work, they all agreed to take all their children to Gu Chu's house to make a mess.
In this way, five children without their parents had a fight together.
The five of them have to stick together all the time, just like the candy. They go to school together, stay in class together, skip classes together. They must be in the same class. They must fight together. They must be admitted to college together. We share difficulties and blessings together. They will definitely become the policemen of their dreams together when they grow up.
Because of an accident, the five people were separated, leaving only Gu Chu.
But Gu Chu unexpectedly returned to the past when they were children, and secretly vowed to change the past of the five people and start to save the fate between them.
