Marriage first, love later + running with the ball + the strong return of top lawyers. The heroine is no ordinary silly sweetheart, but a business lawyer who hides her identity. Her hidden marriage back then was a deal, but she unexpectedly had a child. For the sake of her children and freedom, she faked her death and worked hard abroad to become an industry elite. The male protagonist is not a sick man, but a fake-death boss who pretends to be sick and secretly controls a business empire. The two became the most difficult rivals in the mall. He thought she was dead and she thought he was gone. The reunion was the ultimate showdown. While they were tit-for-tat, they discovered that the other person was the father/mother of their child, and they staged a "cat-and-mouse game" and extreme tug-of-war between two highly intelligent people.
