A straight line was the loudest echo in his youth; a silence was the longest wait in her adult life.
Lin Xiao, a girl from Beijing, has a cool talk and a cool demeanor. In her sophomore year of high school, she went to meet her brother and fell in love at first sight with her brother's roommate, Shanghai Young Master Zhou Yan. With her straightforward Beijing accent and quirky personality, she forcefully pried open this lazy school boy's defenses. The two of them went from fighting each other to being ambiguous, from tutoring on homework to having their hearts beat faster, but before they were lovers, he suddenly disappeared and there was no news at all.
Seven years later, Lin Xiao became the queen of the singing world with her strength, shining brightly; Zhou Yan also broke away from the shadow of his family and became a new upstart in the business world. When they met again, she regarded him as a stranger, but he followed her step by step. Marriage partners, hidden love rivals, injuries in racing, truth-telling and risk-taking... Old love remains, but new flames are rekindled. But why did he leave without saying goodbye? Why did she keep silent about waiting? This is a love game that spans the north and the south, and runs through youth and adulthood - the straight-ball girl eventually becomes a star, and the lazy boy becomes a wife-chaser.
