The girl’s grandmother was seriously ill and needed money. By chance, she agreed to marry a CEO. At the same time, a wealthy family found their long-lost daughter, who turned out to be the girl’s best friend. Now, one is the CEO’s secret wife, and the other is the returned wealthy daughter. But their relationship is no longer what it used to be.
