On the parallel-world Blue Star, 28-year-old Lu Tianchen is a spoiled third-generation heir who lives a carefree life, spending money like water. As the eldest heir to Huanyu Group, one of the country’s top conglomerates, he has never had a worry in the world. After a major business blunder, his grandfather, Lu Zhengguo, orders him to marry Qin Zhiyi, the female CEO of rival Shengshi Group. Hot-tempered and devoted to her career, Qin Zhiyi initially scoffs at the business marriage. But as they spend time together, she gradually discovers another side to Lu Tianchen beneath his playboy exterior. Amid business rivalries, romantic entanglements, and provocations from her ex-boyfriend, their relationship slowly grows from a marriage of convenience into something more. Lu Tianchen, too, transforms from a spoiled rich kid into a mature man who can stand on his own and protect the people he loves.
