Five years ago, Lin Xia ended her relationship with Cheng Yan, the man she loved deeply, after receiving an anonymous letter, and left for Wall Street.
Five years later, she returns as a financial expert, only to become entangled in a massive conspiracy.
Trouble is brewing within the Cheng Group. Cheng Yan's younger brother, Cheng Mo, has joined forces with the mysterious organization Shadow, hoping to fulfill his ambition of controlling global finance by taking over the Cheng Group.
Lin Xia and Cheng Yan reunite amid the crisis. Moving from initial misunderstandings to gradually rebuilding their trust, they join forces to uncover Shadow's layers of conspiracy.
As she investigates, Lin Xia discovers that her own past is secretly connected to Shadow, while the real reason behind Cheng Yan's breakup with her five years ago has also remained hidden.
Hunted by Shadow, sabotaged by business rivals, and caught in a tangle of emotions, Lin Xia and Cheng Yan stand side by side in life-or-death battles.
They must protect the Cheng Group, expose Shadow's true identity, and stop a global financial disaster.
