Nora is a genius AI architect who won the national championship at nineteen. For marriage, she retreats for seven years, helping her husband Ethan's company under the alias "Sugar"—while he ignores and neglects her. Because of a past "life-saving debt," Ethan has always favored his half-sister Vivian, even giving her Nora's research. After repeated disappointments, Nora files for divorce. Ethan dismisses it, certain she can't survive without him. But Nora returns to the AI world under her real name, stunning everyone. Vivian's lies are exposed; her reputation collapses. Only then does Ethan realize the wife he neglected was the one truly holding up his company. He begs for her back, but Nora coldly refuses, reclaiming her life and finding someone who truly values her.
