To preserve her mother’s medical trust fund, Alex was forced to disguise herself as a man for twenty years, acting as the family’s “only male heir.”
At the lavish century‑defining wedding between her vicious stepsister and Julian, New York’s wealthiest man, Julian was drugged. By chance, he spent one passionate night with Alex, who had appeared in women’s attire on that occasion.
Afterward, Julian called off the marriage and launched a city‑wide manhunt for the mysterious woman. Meanwhile, Alex continued to interact with him in her male disguise, kicking off a dangerous game of cat‑and‑mouse.
Eventually, during a family banquet, Alex produced the medical report proving her stepfather’s infertility and exposed the shocking scandal: her stepsister was an illegitimate child. Having exacted her revenge, she fled the city while pregnant.
Six years later, under the assumed name Sienna, she returned to New York with her gifted young son. The little boy deliberately “runs into” his biological father. After numerous cautious tests and encounters, Julian finally sees through her disguise. The two resolve their misunderstandings, join forces to punish the villains, and the whole family at last finds happiness.
