Yvonne, chairwoman of a major conglomerate, had hidden her identity for her husband's pride. After discovering his affair and suffering a miscarriage caused by his mistress, she divorced him and returned to her company as an intern. At the company anniversary party, her ex-husband and his mistress, who were now employees, viciously insulted her. When she revealed her identity to fire them, they dismissed it as delusion, accusing her of being the president's mistress. As they incited others to disfigure her, the real president, who was also Yvonne's brother, arrived to unveil the truth.
