Lin Wan, a delivery worker from Beipiao, takes the surname of Lin from her grandmother who raised her. He was abandoned by his biological mother as a child through a "hide and seek" scam, and was later taken away from the orphanage by his grandmother. Nowadays, she rushes around Chang'an Street day and night, just to save enough money for her grandma's life-saving surgery. Her only respite is working as a cycling anchor "Backwind Xiaowan" late at night. Next door lives the neighbor Cheng Yu, who is hated by everyone but also a dog, and plays games all day and night. In an accident, Lin Wan picked up a rare limited edition gaming helmet (valued at a sky-high price) that Cheng Yu had rolled down, and saw the stock market transactions worth tens of millions on his screen. Faced with the shock, Lin Wan only said "just have fun".
