Erema has been CEO Weissman's most trusted secretary for six years, handling every detail of his professional and personal life while secretly hiding her feelings for him.
When stress-induced insomnia leads her to a new medication, it triggers an uncontrollable hormonal reaction. That night, Weissman unexpectedly falls under its influence, and the two share a passionate night. Panicked, Erema flees before morning. Weissman wakes furious and vows to find the mysterious woman.
At a luxury cruise party, Erema suffers another episode and narrowly escapes assault. Instead of comforting her, Weissman scolds her. Heartbroken, she resigns—not knowing he has already dealt with those who tried to hurt her.
Weissman's life falls apart without Erema. She is the only woman who can make him lose control. When the doctor says an antidote will take three months, she signs a three-month agreement with him.
Their growing intimacy is threatened by Kane, Weissman's younger brother, who has secretly loved Erema for years and joins forces with his mother to drive them apart. As the agreement ends, Erema receives the antidote—and discovers she is pregnant. She hides the pregnancy and disappears.
Yet what began as a secret affair has blossomed into genuine love. The once untamable CEO has unknowingly surrendered his heart.
