This is a first-tier city with an extremely fast pace. Takeaway riders, white-collar workers in business districts, residents in old streets and residents in high-end communities are tied together by the countdown on their mobile phones. Everyone's life is driven by the word "on time". The protagonist was originally just an ordinary rider, desperately taking orders in order to pay off debts and keep his place on the site. However, after an overtime complaint, he was involved in a series of conflicts between platform rules, merchants' price reduction, webmaster assessment, and the "lady" owners of high-end communities. The main line of the story revolves around the 1v1 relationship he established with an eccentric and demanding female business owner who only orders from him for a long time. However, the entire book maintains the daily tone of the male-dominated city, focusing on livelihood, dignity and real relationships in the cracks of the city. As orders are delivered again and again, the protagonist gradually realizes that the rules in this city are not written in the system, but hidden between people.
