At nineteen, Elara was drugged by a stranger and betrayed by her boyfriend and stepsister. Drunk, she spent one reckless night with Alexander, a wealthy heir. She left a hundred-dollar bill as an insult and slipped away without a word. Alexander chased her but crashed his car, losing his memory—only her silhouette and that bill stayed etched in his mind.
Seven years later, her genius son Eli hacks into the corporate system and sends her resume straight to his birth father. Mother and son reunite with Alexander, only to face forced arranged marriages, a rival’s fake rumor that they are blood siblings, and relentless suppression from his grandfather and scheming foes.
With an old wristwatch, crash evidence and his father’s will uncovering all plots, all misunderstandings fade the moment they tear up the hundred-dollar paper plane. The trio overcomes every obstacle and finds happiness. Three years later, they welcome a little girl, living peacefully as a family of four.
